Louie, that rifle you made is superb! And Creamer's locks are things of great beauty. I always thought of the lock as a mechanical device, but you have shown me that they can be, and are, beautiful.
Having checkered a great many guns, I did take a close look at the rifling. The only old rifle that I have was made in 1873, and it also had that flat checkering in the wrist area. What type of checkering tools did you use? Something modified from the normal vee-toothed cutters and spacers?
I do not think I am going to checker the Rupp replica that I am building, but ya never know!
