I have an old Ohio style percussion rifle that was around my Dad's house for about 40+ years. At some point, someone had removed the lock and lost a lock screw and some small parts. I sent it to Jack Brooks because he advertised as providing restoration services. I have no idea what the collector's value of the rifle is but my Dad had always spoke of getting it operable. I sent it to Mr. Brooks and asked that he only preserve it and make it operable. He sent it back looking pretty much like it was when I sent it to him except it was cleaned, well oiled, in one piece, and ready to shoot. I haven't shot it yet but I couldn't be happier with the results. He fabricated the necessary parts, adjusted the triggers, and generally saved it from becoming another lost old rifle.
I intend to post pictures to see if any of the experts here can tell me anything about it. It's a half stock rifle with a lock marked "Biddle" and it reminds me of a Vincent rifle.
