Just for the record here, Brian did not remove any wood from the gun. He said that he mounted the guard on the surface at the rear tab and made it long enough to cover up the chisel marks. As to wood removed, my old eyes don't have their micrometer abilities anymore (did they ever? No!), but if you measure the molding at the toe and consider that to be an original dimension, it would make sense to maintain that measurement as a constant, forward to the wrist. This would make the molding edges parallel overall. The original photo suggests that may have been the case.
Have to throw in here with Chris and JTR. Aren't we arguing over 'angels dancing on the head of a pin?' But, a great discussion here, nonetheless, and it is much what one hopes for on the academic side of the Kentucky Rifle.
We all agree now that the gun has undergone alterations. Too bad, the principals involved knew better, but these things happen. I would not toss it out for that if it came into my hands, and it could be put back to what the old photo shows.
Gary, thank you for going to the trouble of posting the catalog photos. You are an 18th century man well adapted to the 21st century to have accomplished that feat.
