A couple years ago, I decided to rework a Miroku or Ultra Hi .67 cal smoothbore pistol. I believe it was the Continental version of the Japanese "Tower" pistol. I slimmed down the stock, shortened the barrel, added beavertails, moved the ramrod pipe up, and replaced the metal rammer with a wooden one. The idea was sort of to make it look like an American copy of a British Light Dragoon pistol, albeit with a Sea Service style lock, since that's what was on it. Sold it last month to a buddy of mine, but enjoyed it for a number of years.
