Miroku is an excellent gunmaker. It's too bad they got out of the Civil War reproduction business. They made just about the most authentic muskets. I have two Mirokus -- a Model 1863 and a Model 1861. The 1863 had one glaring mistake -- it had both band springs and clamping bands (clamping bands are characteristic of the Type I and band springs, with solid bands, are characteristic of the Type II). I had to find solid upper and lower bands to make it correct for a Type II. The 1861, I ended up converting to a Model 1855 by installing a working Maynard-primer lock. That gun is my favorite CW musket.
