No disrespect intended, but if you're new to PMs, who decided it was in very good condition? What factors were considered? Finish loss, of course. Barrel finish w/slide back? Grip condition, i.e. correct star? Guts? Feed ramp? Rifling?
A picture would give a better idea.
From the era of those pistols, if I liked it, I would consider an upper limit of $1000 ($800 in general) and do every thing I could think of to bargain the price down. If, I really wanted the pistol. 1960 w/matching mags a plus.YMMV.
But then as luck would have it, the Trump administration may allow them (Russian PMs) into the country in the future, lowering their value.
