Dennis, Here is the rifle that I built for my grandson Reuben. I used a Ed Rayl .32 cal. barrel, a original lock. I made all the hardware & built the rifle from a chunk of maple I had around here for several years. I had Marvin Kemper to route the barrel channel for me as he has a set up to do this in a very short time. I couldn't find set triggers that I like or the hardware for the rifle & I made them from wrought iron. The pipes are .25 in the inside dia. If you think these pictures are good enough & worthy enough to post then you can. I have more than 100 hours in this project. I made 3 guards & this was the best of the three. I made 2 rear ramrod pipes & went back to the first one. I made two patchboxs as it was horrible to make these knuckles & get it to function the way I wanted. The barrel is 46 inches long. I have only made six rifles & pistols before.
