While I was cleaning my newly acquired transitional 1950 SKS, I saw two matching two-digit numbers on bolt and bolt carrier respectively.

My 1949 has the same feature:

Interestingly, the number (77) is same on my 1950 and 1949.
Similar numbers are also seen jstin2's 1950 with spike bayonet (through 2nd ibb.co link, pic# IMG 6367:

I wonder if it is a unique feature only on 1949 and early 1950 Russian SKS?
If my '50 wasn't buried I'd check it. Perhaps soon I will dig it out. I have sh#t everywhere right now.

Thank you! I don't know if this type of numbers are only on 1949 to early 1950 SKS. I don't see them on my post-1950 Russians.
None on my late 1950 with the 45 degree gas block.

Thank you! I am curious if these numbers were stamped during initial production or later refurb. And what was the purpose?
I checked my early 50 with 49 features but with blade bayonet and 45 degree gas port. It also has bolt and carrier stamped with #54. It also has a O on the carrier.

I'll check my '50 refurb later today or tomorrow. I would think it is OEM because, if a part of refurb process, one would think all would have the numbers on them. Possible pairing stamp designation for OEM build process maybe???
pcke2000- you should add more pictures of your carbine. This will show how early the transition was made. On page 5, I have pictures of 1950 transitions. I no longer have several of the carbines, so I cannot check the rest. I think that this is something new and interesting to most of us. I did not even realize this marking when I took the pictures of my 50 with spike.
Just checked my EO '50, sure enough...in the exact locations I have what might be construed as a 1, although it's not extremely legible. I never would have thought they were matching marks until you pointed this out.

Well, I've got markings on my '50 as well, but can't really make them out due to the circle swirls from machining. I do have the (1) stamp on both parts like what is seen in pcke2000s '49 pic
Just checked my early 50 with 90 degree, has matching 4. Very interesting.
It slipped my mind, but I have a bolt and carrier from a 50 coming next week...I will have to check that one too.
Just received my newly purchased 1950 transitional Russian. Both bolt and bolt carrier have '77' stamped. Since I have a 1949 and another early transitional 1950 that also have '77' stamped on bolt and carrier, I believe '77' may have some special meanings at Tula arsenal around 1949-early 1950.

Thank you so much for the info of the 1950 transitional!
Gonna toss this out there - Could the marks have anything to do with keeping a bolt and carrier together during the machining and/or assembly process?
As pcke2000 pointed out, these way well be arsenal specific, but I was thinking that they might be from a single machinist or inspector.

Yeah, I brought that question up in my first post above as well.

Well crap.
I did manage to miss that part of your post.

No worries, I think everybody did from the lack of discussion on that point. So, glad you brought it back up.
I actually got a better look at the one I have coming...and I am hoping once the BBQ paint is removed, something will be visible...but, for the time being, I see stamps...but nothing legible.
Matching #2's on my bolt and carrier of the tula no date refurb.
checked the 53' izzy refurb as well and it does not have the side stamped numbers present.
Damn it I forgot to check mine. I'll try today.

Same size, font, and even angle. I tend to agree with the idea of it being something done at certain places, perhaps refurb sites, to keep the bolt and carrier together.
But interesting nonetheless.
'50 refurb shows only a "5" on carrier and I don't see anything else that matches as far as a number or what maybe a number

'51 Refurb has "1" on both carrier and bolt...

'51 Queen has "1" on both but they are not stamped well but I'm confident there are parts of a "1" on both carrier and bolt

No ep on the inside of the extractor claw either
Matching 20 on the bolt & receiver on 1949.
I just put them away but, there’s a 2 on my early 1950

Until I read this post, I did not think anything of these numbers. But when I bought my early 50 with spike (ИМ 3) in Feb. and noticed it's number, I grew more curious. It looks like a Q. Until I can post some pictures from mine, here are some pictures from a 49 to a 51 from another collector.

I took some pictures of my early 50. I do not have macro lens but got some pictures anyway.
