Does anyone have information on flintlocks made by W Estes? The only other marking is #21 on the barrel. Google returned Wayne and Clary Estes associated with flintlocks but haven't found any tangible information. I believe it is .45 cal, Kentucky flint lock with full stock. If this is made from some sort of kit, what should I expect to pay? Attached is a poor pic of the rifle. Any advice would be appreciated.
