Picked up this stock recently. Looks like a milled underfolder but is stamped construction. Blue finish with what appears to be two very faint stamped cyrillic letters stamped on the inside of the buttplate. The arms are more round than my Chinese folder. Any ideas ? Russian? Bulgarian ? Romanian? Also the stock came without the attaching hardware and appears to take milled type parts. Anyone know of a source for the parts?

looks romanian to me

NOT Romanian IMO.
My Romy milled arm stock from CF is parked not blued, doesn't have the "scaloping" on the outside of the arm where the pivot is, and flats at the butt plate pivot are much shorter.

Oh yea, Romanian language is based on Latin from the Romans, hence, ROMANIA.

Crylic letters are used in the Slovac based alphabet.

My guess, Bulgarian or Russian.

Thanks, guys.
