I just got my Romanian stock in and started looking it over. It is in great shape considering its age and the SN on it is super close to the SN of the matching parts! But I see some markings I don't recognize and have not read about yet on these forums.
There are 3 stamps right next to the dust cover.

They are from left to right, an o or zero inside of a circle, a horse shoe with its ends pointing up inside of a diamond, and a star made of 5 straight lines inside of a circle.

This looks like a triangle with some markings in it that I can't decipher.
