I suppose if you had more detailed pictures, showing proofs and inspections, We might be more of a help. Other wise, Gunbroker , Auction Arms, Etc., would be your best choices for comparison.
Could use better pictures. Is the barrel correct and in good condition? If this gun was all original, it would be in the $2000-2500 range IMHO. People try to sell them at $3500 on GB but not many people buying at that price unless it is very clean. Hard to tell from your pictures. Condition means a lot and it might be worth more if in great shape.
A serial number would also be helpful. There is plenty of helpful advice to be had here, but if you could provide the requested info we'll be all too happy to help. And welcome to the Forum!
