The pin may still be under the grips.
Looks nice. It appears that the lanyard ring assembly was just removed. I sometimes see the lanyard ring assemblies, will take a look and let you know.
The date is stamped on top of the barrel.
IIRC, Basically Russian, Chinese, Romanian, & Yugoslavian are the same shape and interchangeable.
Albanian has different shape, a bit boxier, but is also interchangeable.
Serial numbers are all stamped on bottom with the exception of the Yugo which is on side and will have a part number either...
