Allen, I doubt the rifle in this post is the one that you're thinking of. Jerry Kirklin made a documentary copy of the Herman Rupp rifle in the 1970s. I believe it was originally made for Tom Wilson who owned the antique rifle. I visited briefly with Tom in his store in Delaware OH. At that time, Tom told me that he had copies made and sold some of the antique rifles. Some years later (CLA at Fort Mitchell in 2000), I bought the Kirklin copy from Jim Johnston when he was selling several of the contemporary pieces for Tom.
