In the early 1970,s I attended a machine tool show in Chicago.At this show B.C. Miroku was an exhibitor. Their stand featured, hones & barrel boring machines.I picked up literature which unfortunately was only available in Japanese. The literature illustrates their manufacturing process for shotguns and rifles as well as their machine tools. The only item I can decipher is what appears to be a list of customers.It reads as follows:
Browning Arms Company, Fabrique Nationale Herstal S.A., J.G. Anchutz GMBH. ,Norma A/S, HDF-Bolagen AB, Osakeyhito Eloranta, Simonen and Nielseon A/S, Carm Espanol S.A., Goess&Co,GES,MBH., Fuller Firearms Group PTY,LTD., Douglas and Johnson & Co, Ltd. Browning France S.A. Borsumij Sports B.V., Afdeling Browning.
Browning guns and rifles are illustrated in the literature. Some of the companies listed are likely customers for their machine tools.
