The barrel on my Hex Reciever C.A.I. Import does not have a date. When did they start stamping the manufacture date?

Ok, the letters and numbers are a bit worn off. What looked like 1990 to me, is actually 1920. The hex receiver is also of that era wire no plugged grease hole.

Pull the action from the stock, flip it over and look at the rear tang of the receiver where the action screw passes through it. There should be an arsenal stamp and the last two or three numbers of the date the receiver was produced.

https://thinlineweapons.com/7.62x54r/7. ... D/0104.jpg mine looks like this. I’m pretty sure it’s 1920 on mine. Numbers almost worn off. The numbers under the tang are to small for me, it almost looks like 1916.

1920 is a pretty uncommon date. Lots of turmoil going on during the Russian civil war then. They recycled lots of receivers then so a 1916 receiver on with a 1920 barrel makes perfect sense.
