if its matching ( east german matching, ) all serials numbers match $800 easy, since its MDI marked I would go higher,

I dont need to see the under the barrel now, I would like to see buttstock pictures

I collect these, it would go nice in my collection

the rule of thumb is, even by me, East German rebuilds and russian reworks are shooters. This is true, except certain rifles and handguns were issued to different security departments, why they command higher prices.

good luck
