Pukka...If Japanese, (Mirouku) it should have a slightly bent or miss-shaped trigger-guard.
The Japanese copied their example exactly, including the bent guard.
Also if Japanese, very light and well made musket!
Yup. I remember the eighties where I Captained Rogers Rangers Boat #17. We all wanted Kings Arms and nobody cared that we were carrying the 1770's model. I could not live with the dented trigger guard. I ended up putting an Italian Guard on it to make it look right.
What I loved about it was that the cockpiece throw was short so striking the Frizzen did not throw off your aim. This was back in the day when everybody was cutting down muskets, just before everybody hadda have a Tulle...
