Some of the early Miroku box lock guns were not marked with a model number. This is as much as a scallop as I have ever seen on a Miroku, later guns had simpler straight stock to action fitting. Ejectors and single triggers don’t seem to turn up that often on the older guns, a good thing in my opinion.

Likely a decent bird gun, not flashy, but, very useful.

Best,
