Sorry I didn't respond on SW forum, it hasn't been working for me the last few days.

These guns are definitely different from the standard production guns like the Miroku, SKB, BSS and Winchester 23's. These guns were built in small numbers by a number of shops, much like the English gun trade. They have excellent wood and metal fitting, as well as hand engraving. Mine are all light and very nice to shoot.

John Mann, a poster on this forum, did much to educate me. Some of his posts show up in the threads below.

Here are links to previous threads on this type of gun:
