Cannon
I like them and always thought they looked "super cool". Around 50 years ago I bought one, didn't know much about them. I brought my treasure home but upon inspection I noticed the barrel was bored offcenter. Just looking at the muzzle showed just how crooked the bore was. I sold it not long after. My memory is a little foggy on details but I discovered/became aware of it being a cheap import. If it had been as nice as yours it would still be with me.
