Try Jerry Andrews. He has built me two forends from scratch. One for a 20 gauge LC Smith 3E and one for a A P Curtis gun that I do not believe was ever put into production. Had the busted forend which he dupicated. Wood matched both guns perfectly, fast and reasonable. Here is a link to a Forum he started.
