Mine is a Centermark. They come up for sale fairly regularly on used and auction sights. They are not 100% correct. Biggest most obvious things "wrong," are that the stock is usually maple and should be walnut, and the barrel is a few inches too short. There are a few other issues according to the "experts." Some issue about the size or bend of the trigger guard and a couple other things I still have trouble spotting and remembering.As far as being correct, not really sure because I just got interested in them. I guess it would depend on the what shape the gun was in and the price. Just going to be used for hunting - no use in historical settings.
Caywoodguns.com have the best flint locks, from Arkansas. Their ads used to have a photo of Gov Huckaby hunting turkey with one of their top grade flint fowlers. I used to shoot one of their small rifles. Can vouch for lock, general high workmanship. Believe I still have one of the locks they use, from my building days.Any suggestions on where to buy one?
