WTK What is this Czech 52-57 worth

http://i262.photobucket.com/albums/ii110/KEVAKOV/100_0878.jpg I have a chance to get this Czech VZ 52-57 rifle in 7.62x39 from the She arsenal. Its from 1959 and is new and unfired, a very nice rifle with no import marks at all. No corrosive ammo has ever been through it. Just wanted to know what its worth. Thanks.

You say, it's new, then it's never had any corrosive ammo fired through it!
So it cant be new, it looks very nice but not new!
If all is correct, from the picture i would say it is a refurb! For that one, $500. is fair!

I have seen some for sale, that went for $150 to $350 because they had dark bores from corrosive ammo, this bore is very clear. I think you are right about the refurb redo because the bolt and front top cover are black and not the grey color on most. And you are very close on the price. Thanks for the input.
