I used D'Arcy Echols to copy a J Blanch & Son back action ejector, both stock and forend. It came to about $650 about a year ago.
The professional hand stocker who did the final inletting was very impressed with how little he had to do to finish it off and apparently the wood looked nice but was horrible to work! (my fault not D'Arcy's)
