Here are some photos of my half scale Napoleon. It's not a nut and bolt replica, but it's a shooter. It's a Dixie tube, and they had the cast iron bore sleeved with seamed water pipe. I took it to a machine shop and had some seamless tubing turned down to fit inside that, and it still gives me a 2 inch bore which is also half scale. I bought the wheels off ebay, and built the rest of the carriage myself, including the iron work. It now sits in our front yard at the base of the flag pole, the only cannon in the neighborhood. I flew the flag at half staff at Reagan's funeral, but I didn't get a photo of the gun going off then because we were all busy, but I fired it when we raised the flag back to full staff. The photo of the gun firing is a blank fired later just for the picture. I have a five gallon bucket of 2 inch ball bearings for ammo. They just fit the bore, but I can't hit a darn thing with it. I think the tube has some run out that I can't get on top of. Anyhow, I mostly shoot blanks, so it doesn't make that much difference.
