Old parker DH damscus- whats it worth

[jsd245]

I love the look of damscus barrels. I always wanted to try my hand at restoring a gun. So I've run across a parker DH 12ga that dates from 1890 I haven't had a chance to see he gun. I've seen pictures and its very very rough. Its hard to get any details from the seller. I think the barrels have a couple dents. Original wood is there and looks OK, action is pitted a bit but there is basically no finish left. So lets say this is the case- barrels are no good, maybe mechanically its OK but the finish on the receiver will never get perfect. I figure this would be a good gun to try to learn how to do some restoration on. Maybe at some point fit another set of barrels on it. If I screw it up- I'm not real upset.

What would you parker experts pay for a gun like I've described?
