I dug this old thread up because I think I just found an example of the round in question. It has a GMCS bullet, CWS case, brass primer, and a raised ‘60 51’ headstamp. The paint is not in good condition, but I think it clearly shows the correct markings.
Jon, 1951 is too late for Russian silencer loads (for the “Bramit” silencer) as the Russian stopped making the cartridges in about 1942 due to ineffectivity (as they been using the “L” light ball - the Finns copied them and made the same error).
Also the green tone does not match (original was like the green you see on tracers - same laquer I assume) and the original silencer load had an all green case head and an all green projectile which extended well over the case neck.
Do you have the possibility to x-ray your cartridge?
A. The paint looks original to the round; down into the case mouth and around the primer.
2. What would that paint scheme be used to instruct for?
III. The guy I got it from has had it for many years and he’s now just breaking up parts of his collection. I doubt it was faked before he got it, and I’m sure he did not create it.
Green on Russian Ordnance is denoting inert components for dummy purposes (as some other colors do too).
This could have been made in a unit’s workshop if this one is inert and as said many countries altered ammunition for what ever purpose. It may become very difficult to positively ID this one.
I did not say it is a fake.
