Bill,
Based on the photos I think that you have done an excellent job! I have a young friend, Billy Harkins, at home in Union County Georgia who has made several Gillespies, and somehow I'm going to get these photos to him. (He doesn't have a computer). Dennis knows him. He and I scour the Mountains looking for original Gillespies, and so far have found 4 or 5. What you have created here falls right into place with what John and James Gillespie made in Union County before the WBTS.
I'll try tomorrow to photograph one of the Gillespies that Billy has made with an original on the bench in front of him, and you'll see that your rifle is a dead ringer!
