I have a Russian 75RD drum for sale.
95%, some slight wear, mostly on the round pieces in the middle and the loading lever.
Not Polyany marked (or if it is, so faintly that I can't see it) but the SN is in Cyrillic. Lots of other little markings on it too. Finish is black enamel paint.
Paypal +3% or MO is fine. No trades please.
Front of the drum showing some of the markings. I can't tell what most of these stamps are.
ETA more pics added.
