From the lack of markings I suspected that it may have been bought overseas and brought back. The barrels say 12 gauge, 2 3/4" on one side and Miroku Firearmes Manufacturing Co., Kochi, Japan.The bottom of the receiver says B.C. Miroku. The choke markings lead me to believe that it is imp. cyl and mod.
The choke gauge tells me full and mod. I guess I will have to pattern it to find out. I hope it is imp. cyl and mod. Makes for a better quail and dove gun.

Thanks guys!!
