I ran across this while doing the September GB listings.

Nothing fancy about the gun, in fact the auction is bonafide 'horsetrash' in the lack of detailed photos. One particular image did get my attention though:

I'd not seen a "RE" prefixed gun before. This one is likely a 1960 gun if it matches with the RA/RB/RC & Rd's. If they went alphabetically, it may be one of the last produced.
Thats an RB... I can clearly see the right portion of the letter making a B

Good eye! thumb1
I have RB 1247. Its a 1960. So the two guns were probably in the same building somewhere in Romania at the same time. thumb1
