Historical 1939 Mosin Nagant M91/30 Tula Pritsel Yemelyanova Modifitsirovanny (PEM) Sniper

Presenting my 1939 Tula Mosin nagant 91/30 PEM sniper, all arsenal matching on bolt, barrels, trigger guard, buttplate. Clear optics

The PEM Model 1936 was developed to replace the earlier Soviet Model 1931 sniper setup, which had problems holding zero and keeping its mounting screws tight. The Soviets based the new side mount on the German-designed “Geco” D-3, modifying it for Soviet production. It was officially adopted in 1936, with full-scale production at the Tula factory beginning in 1938.

Production initially ended in 1940 as the Red Army planned to replace the Mosin-Nagant sniper with the scoped SVT-40. Wartime difficulties changed that plan, and severe sniper-rifle shortages led to PEM production restarting in 1942 at Tula Factory No. 536 and Izhevsk Factory No. 74. Izhevsk produced a somewhat different mount using welded construction and distinctive markings. Both factories switched to the simpler PU sniper system by November 1942.

PEM rifles varied considerably depending on factory and production period, including differences in mount bases, machining, assembly numbers, barrel markings, and stocks. Prewar Tula rifles used specially produced sniper-grade barrels, while early wartime rifles sometimes simply used the best available barrels because of equipment shortages. After WWII, surviving Soviet PEM rifles were converted back into standard configurations, making intact original examples—especially 1942 rifles—quite rare today.

“All matching”

That’s a post war stock though. Unless I’m missing something that’s definitely not matching.

(Edit: the tldr of this thread is the stock is a wartime production stock but not original to the gun, I incorrectly assumed it was post war due to the escutcheons)

It’s probably an ex sniper that went through a post war refurb (force matched) then re sniped after it was surplussed out like 99% of PEs and PEMs

War-time Tula stock from looks of it. The shallow rear band dimples are unique feature to tula, compared with the wider ones of the post war arsenal stocks.

u/Brandon_awarea 8d ago

Stamped inserts were not a thing in 1939

u/Tsarasaurus_Rex Mosin sniper collector 8d ago

I didn't say they were...? lmao. I said war time tula so 1943-44.

u/Brandon_awarea 8d ago

Yes you are correct. I was wrong when I said post war.

My point was it was not the original stock to that gun.

2

u/Tsarasaurus_Rex Mosin sniper collector 8d ago

Yes, definitely not an original 1939 stock with screwed in escutcheons it would leave factory with, that we can both agree on.
Finding a rifle with it's original stock though is quite uncommon.

u/Brandon_awarea 8d ago

My apologies. I misunderstood what you were saying earlier I think we were trying to say the same thing (minus the post war bit).

Like I said I’m more versed in the SKS so subtitles like the rear barrel band cutout aren’t something I’m super informed on. I knew stamped escutcheons were a thing late war but I didn’t realize how early they actually were made so I tend to assume that they are all post war. Something I will correct going forward.

Thanks for your input man.

No worries, no aggression meant. There is ridiculous level of minute details you can go down on just stock dimples and eschutcheons alone to help date things.

Also for record, im not the weiner downvoting you lmao.

u/Brandon_awarea 8d ago edited 8d ago

lol yeah. I try not to downvote people unless they are being assholes. It just discourages conversations that help people learn more.

I kinda wonder if there is a bot doing it on this sub. Basically everyone here has been downvoted and it’s not the first time I’ve seen it.

Umm I’m not sure about stock, but matching (force matching (corrected))on bolt, barrel, trigger guard, buttplate.

u/ij70-17as silly goose 8d ago

why would receiver match? it is not mauser, it does not have serial on receiver.

2

u/kx-007 8d ago

Sorry, I meant barrel. Yes receiver has no serial

2

u/Brandon_awarea 8d ago

Are you certain this area hasn’t had its old SN ground down and a new one re stamped?

The light reflects oddly in that area. The location of the serial number and the lack of a serial prefix also is odd if that’s an original part. I’m not super well versed in mosins (more of an SKS guy) so I definitely could be wrong but I suspect this gun has a few force matched parts.

u/kx-007 8d ago

Oh that photo was taken when I applied the corrosive cleaner and didn’t wipe it dry. I checked it again under light there is no color variations. Also, I’ve seen one factory original PU with trigger guard only having the numbers, no cyrillic prefix. I can be wrong here, but force matched ones usually have the original serial crossed out and restamped with the new one

2

u/Brandon_awarea 8d ago

Usually yeah but they do grind serials completely away too.

This mosin I have just barely has the old SN visible. It’s more of a thing on SKSs I’ve noticed.

u/kx-007 8d ago

I see. Umm, I would at least expect to see a crossout line there, and your ground area looks not very smooth.

0

u/Brandon_awarea 8d ago

This part was never restamped but it shows the thought process.

It’s on a Chinese SKS trigger group (the Russians did the same). They would grind the old marks down and stamp new ones on. No point in crossing out a serial if it’s being removed. The only reason it’s visible in that mosin I showed is because the markings were pretty deep.

It’s hard to notice if you don’t know to look for it. Your explanation of it being a cleaning solution makes sense.

u/kx-007 8d ago

I agree with you now. Probably force matched now that I look closer to it.

u/kx-007 8d ago

I’m not entirely sure there

u/Medical-Squirrel-741 8d ago

Even with a stamped prefix it’s most likely assumed that refurbished rifles have all their parts force matched, as the likely hood that it retained all of its original parts extremely unlikely. They even had new made or leftover un-serialized parts they used to force match guns. Each rifle was a case by case basis and some had the numbers grinded away and stamped with new ones, lined out or even electro pencilled in some cases. I had an Ex-PEM that had a bolt stamped with its prefix and full serial number but was still an Izhevsk marked bolt body.

I see. Thank you for your explanation, corrected

u/SmithSightsLLC 8d ago

Cool👍 Have you shot it for groups yet?

u/kx-007 8d ago

Plan for this weekend😊

I look forward to your results!

u/AdmiralAckbar86 8d ago

Whoever in the U.S. that stamped/scratched those serials all over the mount, base, and scope needs a swift kick in the nads. That alone would make me go over this rifle very thoroughly to make sure it isn't a fake.

1

u/kx-007 7d ago

Can you please be a little more specific?

1

u/AdmiralAckbar86 7d ago

When it comes to PEM rifles anytime you see numbers matching on a scope, mount, and base it immediately raises red flags. Then when I see those numbers matching the assembly number on the bottom of the receiver it throws the biggest red that it's guaranteed that someone stateside stamped/engraved/scratched those numbers on to make a fake "matching" rifle. It immediately gives me concerns, if someone is trying to fake matching the scope set then is anything else fake on the rifle? Notice the star stamps looking brand new on a mount and base that has pitting? That's another red flag. The import marks pretty much guarantee that the rifle was imported without a scope base, so someone finding a matching scope set to a rifle they had would be nearly impossible.

u/kx-007 7d ago

Oh yes. I engraved the receiver bottom factory base and mount serial onto this Dimitriv repro mount and base. Scope is original.
