SKS Barrel/Receiver Index Numbers Identified and Verified

[Greasemonkey]

Less then 24 hrs and we will know one way or the other.   

Damn... down to hours and minutes... it's like birthing a kid.. the overly nervous anxious anticipation. Come on myth.. I wanna see a big arse Mythbusters, this myth is "CONFIRMED" sign.. Not "Plausible", not "Busted"...   and just to piss the world off.. "We was right"

Vote now if you haven't as of yet.

While we are waiting...

My /606\ 1.4m with a short lug has an 8 on the barrel, and a lightly struck, and/or damaged 8 on the receiver...I think.  It easily might not be stamped on the receiver at all and the nick and bluing rub there might be messing with my eyes.  The 8 on the barrel is pretty darn tiny compared to others I have seen.

The witness mark lines up, but do not appear to have been struck at the same time.
Replacement barrel?  It sure doesn't look replaced...bayonet handle wear on the muzzle and not so sharp rifling makes me doubt it.

Thoughts?

When you get done, and when Gunboards forum issues are all resolved (if ever), please post results over there.  Should be an eye-opener.   Thanks.

... and waiting.  C'mon already!!!

This isn't going to be fake news, is it?  I can't vote again in the poll.

Murray will verify the results later.....

Voting has been locked.  Stand by.... errr, Hurry up and wait.

Yay 
This would have been unsolved forever if it hadnt been for you meddling kids!

[martin08]

No photoshop there.  Good work all.

Next job.

How did the Yugoslavians do it?

Sticky Time!



Excellent work!!

And Thanks to Murray for the assistance.

Now I'm curious if there is any international compatibility.  And for that matter if late Chinese threaded barrels (short and long lugs)  and early recievers and vice versa.

I know m08 decribed mating a Chinese barrel to a Yugoslav action, but are thread pitch and spacing the same between all the national variants?

Next job.

How did the Yugoslavians do it?

The only thing I can think of is they do it like Ben Murray does with the NOS 59/66 barrels on the market. Those barrels  come with no flats no extractor cuts, and no gas port.  He has to index and torque the barrel, machine the flats while installed, remove the barrel to cut the extractor, then adjust headspace where necessary. 

Its worth noting, I bought one of those barrels myself and there are NO inspection stamps which you would think at the state of completion there would be.... so Im not sure if they were even finished.

It could be those barrels were not completed and Yugoslavia could have simply used an ink stick or pencil to mark the barrel and these numbers were later removed during the finishing process.

Also, Considering they only had TWO facilities doing rework on their guns, these numbers may have been redundant for them to stamp.

In addition  .....   They COULD have found the physical numbering of the parts impractical since they were to be placed in a corresponding numbered bin. 

One thing the Chinese mastered....  QC the part, dont waste time marking because the entire bin its going into is marked. 

[Boris Badinov]

Maybe the Yugoslavs used numbers on twist-tied, hang tags instead of stamps?

Very well possible..... I can think of several ways in which they could have been labeled or organized into bins without the need to physically stamp them.

This is just beautiful hypothesis driven, empirical testing, grade A knowledge generation! Stellar work!
