Will, I believe the company making Ithaca o/u and sxs shotguns in the 60s and 70s (later SKB), was named Mitsui. At least that name came to mind when I read your post. I'll see if I can find out more and I'll get back to this thread if I do. I know SKB made the Ithaca doubles because I had identical guns, except one was marked Ithaca and the other SKB. B.C.Miroku makes the Browning BSS (and made the BSS sidelock) and Citoris.
