Heres my quandry on the gun. It has the lines of a late flint period Lehigh Valley gun. It has the oct. to round barrel. Although not an unadorned "barn" gun, it is simple, no patchbox, no carving. The lock is an 1850 era percussion, a poor conversion. Lock is from a well known hardware store of that era, and so marked. The lockplate on the left side is the common brass lancaster type 2 screw of the late flint period. I think its obvious the gun began life as a simple mans flintlock, a farmers gun, but besides the bad percussion conversion, the gun seems of very good quality. I guess I am wondering whether to buy the piece because I'm not getting a clear picture of what it really is. Make any sense?
