I am planing to engrave a special project. It will most likely take me a year to do. It is a spec gun. A colt revolver percussion type. I have three options on the gun. One is to do a reproduction. The other is a second generation colt. the other is a first generation colt. I really don't care what the cost is. What I want to know is when I sell it would I get a lot more out of the original ? Or does it make a lot of difference in the sale price? Sam W. or Sam Alfano should know . Can;t get in touch with Ron Smith.
