My cannon is not historically correct since it has rubber tires, but the barrel is made from a scrapped M3 37mm anti tank rifle barrel. Guy I bought it from had a couple of chunks that had been cut into 36" to 40" sections. The barrel for this one was the muzzle end of the rifled barrel. I put a pintle ring on the steel carriage and pull it with my jeep or truck when I need to transport it. I bought one of the brass cannon lanyard/hammer locks from Dixie, and set-up with a musket nipple and fired with a lanyard. This set-up works great, instant, and no misfires.
