My Good irstswar -
What you have is actually rather infamous. It is an early attempt by Miroku to produce a replica of the 1803 Harpers Ferry Flintlock Rifle. They failed in so many ways it is actually sad - please allow me to itemize:
- the stock is a "two piece fullstock" and it should have been a half-stock with an underrib
- the guard is close but not quite right - you need to see a real one next to it.
- the lock is a clunky thing with way too heavy trigger and the frizzen is seldom hard enough for good sparks.
- finally , the barrel is an insane clunky affair. Rather than an elegant tapered octagon-to-round it is actually an overly thick untapered
2 piece affair that
screws together, leaving a step inside the barrel!
I handled one about 6 years ago at a pawn shop - it was incredibly heavy and clunky. One could feel the step inside the barrel with a cleaning rod and oiled patch.
the 2 piece barrel was a subject of such controversy that it was actually banned at many rondies and shoots. Amongst the hivernaughts , the theory was kicked about that someone in Japan who had no knowledge of BP guns was put in charge, and that the management thought they were only "wall hangers" .
Many folks consider them unsafe to shoot due to this barrel design.
Miroku has put out some very high quality cartridge guns but the Miroku BP designs seem to be of hit-or-miss quality - it is as if they assign someone to the BP devision for punishment....
