No4 Mk1 Serial Numbers

Hello Everyone,
I'm new to this forum and making my first post. I am a novice when it comes to these rifles and any help would be greatly appreciated. A coworker lent me his No. 4 Mk1 to research. I took a bunch of pictures of all the markings I could find. My first observation is that all the metal parts were painted black. Initially I thought rearsenal but then I noticed many stamps contained paint in them indicating they were painted first then stamped second. Next I did not see any markings on the wrist guard where I seen them on other rifles. The serial number is stamped under 'No.4 Mk1 (F)' on the side of the receiver. What appears to be import markings are stamped to the left of the serial number on the receiver. The bolt and magazine have matching numbers. The bolt has a '0' stamped on the head. The butt plate is brass. 'M' is stamped on top of the receiver. There is also 'something' 79 on top of the metal part of the upper hand guard. I was wondering what the country of origin is, year of manufacture, and what these markings mean. Any help would be greatly appreciated. Thanks.

The receiver. On No.4’s the serial number will be on the left side of the wrist, and sometimes on the left receiver wall. On SMLE’s, the serial number will be on the front and right side of the receivers, by the barrel. The rear of the bolt handle. On SMLEs, the nosecap will be serial’d as well. The magazine. This is a Lee-Enfield No.4 Mk1* (read as number four, mark one star). The WS on the butt stock was added after its military career. Serial numbers are stamped on the left side of the butt socket. Late war Savage No4 Mk1* rifles are nearly always without a year of manufacture, based on serial number surveys these are estimated as 1944 production. The first rifle contract was for 300,000 No4 rifles at a cost of $75 each and of the 96 parts required to complete the No4 rifle about 86 came from 30 parts sub contractors. The serial number is stamped under 'No.4 Mk1 (F)' on the side of the receiver. What appears to be import markings are stamped to the left of the serial number on the receiver. The bolt and magazine have matching numbers. Long Branch (Canada) serial numbers incorporate an 'L' in the serial number while US Savage numbers include an 'C' in a similar relative position amongst the numbers. Both of these No.4 rifle series commenced with 0L1 and 0C1 respectively.

Ok, so I want to start off by saying that this is simply an entry level guide to buying these rifles (hence “Beginner's Guide”). I am going over nothing particularly comprehensive, nor will I really go into the history of anything. I also won’t really be going over the less common variants, such as the Long Lees, early carbines, and sniper rifles, since this is a beginner’s guide. I also have very little experience with buying Long Lees and whatnot, so I do not feel like I have the credibility to discuss the matter.

4 Mk 1 and No. 4 Mk 1* rifles were upgraded to Mk 2 specifications. These rifles are marked either No. 4 Mk 1/2 or No. They will also be marked FTR meaning Factory Through Repair. Golden State Arms Co. Imported huge numbers of SMLE Mk III* and Lee–Enfield No. 4 rifles and converted them to civilian versions of the No. 5 Mk I and general sporting rifles for the hunting and recreational shooting markets in the US, marketing them as 'Santa Fe Jungle Carbine' rifles and 'Santa Fe Mountaineer' rifles, amongst other names.

Some basics

Serial Numbers Office

First thing to cover is basic fundamentals of purchasing a used gun. You know, check the bore, the condition of the wood, overall condition of the metal, how the action is, and bring a dummy round to make sure the chamber is how it should be.

Next thing I want to address is one of the basic Enfield buying rules that /u/Caedus_Vao taught me, and that is the $300 Rule: If it’s in good condition, matches, $300 is a solid deal. If it’s a tad bit more, keep in mind that a lot of people selling used guns (individuals or dealers) are willing to negotiate on shit like this. If they won’t wiggle, and if the Enfield is nice and matching, don’t be afraid to pay more than $300. I recently purchased two Lee Enfields, a Fazakerly No.4 Mk.2, and a Savage No.4 Mk.I. I paid $375 and $500, respectively, but I feel I did well on those purchases, especially on the latter.

I always consider nice old guns as investments, assuming you buy them for the right price. You may not buy them for that purpose, but they are no longer being made, and there is always a market for them, so the prices are only going to go up. As /u/R_Shackleford would tell you, even something as cheap as a Mosin would be a decent investment, seeing a 50-75% gain in value in the past three or four years. The price you buy the gun at and the price it could be potentially sold at are two things I always consider when buying a C&R gun, which is why I pretty much only buy my guns below market value. Buying at market value isn’t a bad thing either, since like I said, prices on milsurps will only rise, but if you sell within the year, don’t expect an immediate return. Also, who doesn’t like to buy things at a lower price? Buying overpriced items however, is something that I avoid at all costs, and you shouldn’t buy overpriced shit, whether you want a shooter, or if you want to collect/invest in stuff. There will always be a better deal somewhere, so be patient.

Be patient and don’t be afraid to walk. Don’t rush yourself into buying a Lee Enfield because you really want one and demand the immediate satisfaction. You will regret that. Take your time, do your research, know what you want, and shop around. If you’re trying to negotiate with someone and they won’t budge, and the price is more than you would like to pay, just say no; you aren’t losing out on anything for doing so.

Matching serial numbers

Matching serial numbers is always a plus. For someone very new to the milsurp market, a lot of guns like Mosins, various Mausers and clones, Lee Enfields, Lugers, etc, will have certain parts with serial numbers that should match the receiver’s serial number. On Lee Enfields, there are various places to look:

  1. The receiver. On No.4’s the serial number will be on the left side of the wrist, and sometimes on the left receiver wall. On SMLE’s, the serial number will be on the front and right side of the receivers, by the barrel.

  2. The rear of the bolt handle.

  3. On SMLEs, the nosecap will be serial’d as well.

  4. The magazine. Sometimes, magazines were not numbered from the factory, especially on No.4’s, so if you don’t see a serial number on one, don’t panic. The magazine serial number will either be on the spine of the magazine, or the bottom of the magazine.

  5. The foreend will sometimes be numbered as well, but there are plenty of them that don’t have numbers. Like the magazines, especially on No.4’s, having no number on the wood is fine.

  6. Barrels will often be serial’d as well. Sometimes they don’t, and will just have the barrel manufacturer and year on them.

I don’t think there’s anything wrong with non matching rifles, but from a standpoint of collector’s value, they don’t carry much weight. I would never pay more than $275 for a non matching rifle, although if it was the magazine, I don’t make too big of a fuss. A No.5 Mk.I is the one exception I will make, but even then, I probably won’t pay more than $350 for one. If do just want a shooter or a woods gun, a non matching rifle will be fine. Non matching is also a great point to use when negotiating price.

Manufacturers

There are many many manufacturers that you will potentially run into, and you can check these by looking on the right or left side of the wrist, or the left receiver wall. Mk.III and Mk.III*’s will typically tell you on the right side of the wrist who made it. On rifles like No.4 and No.5’s, you may be left up to manufacturer codes/markings, so I’ll give you those. I’ll also give you what manufacturer made what (within the limits of this post).

Ishapore - SMLE Mk.III, Mk.III*, 7.62 2A - RFI, GRI, IS, ID - I do want to say something about Ishapores. There seems to be this stigma against Ishapore rifles, and how they are allegedly lower quality than others. I would like to say that is blatantly false. Pre independence rifles (pre-1947) were all subject to strict British manufacturing standards and quality control, and even post independence, the quality control from the factory and government were very good. They may look hideous because of all of the suncorite (thick black paint that looks like tar) slathered on the rifles to protect them from India’s environment, but they are every bit as good as their British counterparts.

Pakistan Ordnance Factory - No.4 Mk.I, Mk.2 - POF

So now, at last, I’ll go over the models, and pricing.

Most SMLE’s will look like this, with the full mannlicher style stock, the bulldog esque nose cap, and the rear sight protectors.

Actual Mk.IIIs are actually pretty hard to find now, or at least examples with the Mk.III features, and have not been updated to Mk.III* spec. An original and true Mk.III will have four key features that will distinguish it from a Mk.III*: magazine cutoff, volley sights, a rear sight adjustable for windage, and a stacking swivel on the nose cap. Rear sights adjustable for windage are pretty rare, as are volley sights, as those were the first two features to get scrapped during war time. I wouldn’t say magazine cutoffs are exactly rare, but they are fairly uncommon. Nose caps machined for stacking swivels really aren’t uncommon, and they are sometimes even featured on Mk.III*’s.

For a Mk.III with any ONE of those features (except the stacking swivel), I would pay $350-400 (kinda low), assuming it’s matching, and in decent condition. For any combination of those parts, or all of them on a rifle, a rifle should be fetching $500+, again, condition pending. Of course, for a Mk.III with none of those features, it has just as much value as a Mk.III*, so $300 rule.

No magazine cutoff, no windage adjustable rear sight, no volley sights, and maybe you’ll find a stacking swivel. These are exceedingly more common than Mk.III’s. Pretty bland. Check condition, check to see if numbers match, $300 rule, but I wouldn’t mind doing $350 for a nice one.

For both Mk.III and Mk.III*s, you may find wire wrapped rifles intended for launching rifle grenades, and those MAY fetch more than regular SMLEs, going for $350-400, but still apply the $300 rule if possible. More if the grenade launching cup comes with it.

You’ll see these rifles fairly often out there, probably more so than an SMLE (at least in my experience). These are most commonly identified by having “No.4 Mk.I” written on the left wall of the receiver, the receiver mounted rear sight, usually having a large battle aperture, and an elevation adjustable smaller aperture (200-1300yds), the exposed end of the barrel, and a bolt release tab under the rear sight on the right side of the receiver. Most No.4 rifles will typically look like this.

One of the more notable things you should be looking for is a milled Mk.I micrometer rear sight. They are much better looking, more precise, and resemble a greater care for quality in No.4’s. You’ll usually see these in early war and post war rifles. Here is a picture from Ian Skennerton’s book to help you identify the other shitty stamped sights you will find..

You may also run into two different types of barrels: a Mk.I and a Mk.II barrel. The Mk.I is the typical five groove Enfield barrel, and the Mk.II is the two groove bore. People like to bad mouth the Mk.II for being inferior to the Mk.I, but the Mk.II was tested with Mk.VII ball, and it was determined that the accuracy with the standard issue Mk.VII was effectively identical the the Mk.I barrel. There is nothing wrong with either. If someone like /u/CoyoteBrown says otherwise, call him a faggot, especially if it’s /u/CoyoteBrown. Another nice thing to have a No.4 Mk.I is the GRIPZONE™ on the lower handguard, being largely an early war feature.

If you see a Savage or Longbranch No.4 Mk.I, and you can get it for <$700, you fucking buy it. Savage only made about 120k, and Longbranch about 7-8k. These are rare and desirable rifles. If you’re lucky, most dumbasses won’t be able to tell, or won’t give a shit about the significance/rarity, of a Savage or LB No.4 Mk.I over a Mk.I*, so if you do see one for sale, try to play it dumb and snag that bitch.

$300 rule applies, but you’re going to be cutting it close. People will typically sell these for $300-400, and if you’re paying $400+, it better be a pristine fucking No.4 Mk.I.

These rifles were only produced by Savage Arms and Longbranch Arsenal. As the * would suggest, the Mk.I* was a cost cutting rifle that was adopted due to the lower cost and shorter manufacturing time. These rifles are easiest identified by “No.4 Mk.I*” being stamped on the left side of the receiver wall, just like where No.4 Mk.I would have its markings. Savages will typically have a C prefix serial number, and Longbranches will typically have an L prefix serial. Mk.I*’s also have a cutout in the bolt guide rails to remove the bolt, and lack the bolt release tab beneath the rear sight. These rifles will also usually have shitty stamped sights, and lack the GRIPZONE™.

There’s nothing inherently wrong with Mk.I*’s, but the simple truth is that collector’s value is not that high for these. Most will typically sell (and rightfully so) in the $300 ballpark, so use that rule.

The biggest between these rifles, and the Mk.I series is that the trigger is hung from the receiver instead of the trigger guard. This helped alleviate some accuracy issues in the rifles. You’ll usually be able to tell a Mk.2 from a Mk.I by the screw that goes across the rear of the stock from end to end. Mk.½’s are Mk.I’s that were updated to the hung trigger, and Mk.⅓’s are Mk.I*’s that were updated to the hung trigger. With both those rifles, you’ll typically see the original manufacturer stamp on the left side of the receiver being crossed out and the new designation stamped on it.

Serial Numbers For Electronics

These rifles will typically have the five groove barrels and milled rear sights. Furniture will usually either be beech or walnut, and I really think the light blonde beech wood contrasts the heavy black paint really well on these rifles.

Mk.2 and Mk.½ pricing should be very similar to Mk.I pricing, but Mk.2’s tend to be in better condition than Mk.I and Mk.½’s, so they will usually sell for more. In fact, most Mk.2’s I’ve seen tend to be in absolutely fabulous condition, looking like they’ve never been used (and they probably weren’t, or at least that heavily).
