I bought this last week and cannot find anything like it on the internet. Who, what, when & where did it come from?
The bore is 10mm dia by 4.5" long. About 3" in, the barrel chokes to about 6mm dia. The choked area extends to the ignition hole that is about 1.5-1.8mm. This chamber holds about 20gn of FFFG. The entire build is brass & wood. Is this a kit?
