Dakin was located somewhere in the midwest, before the San Francisco location. I can't remember where. Sorry.

Dakin also imported Antonio Zoli shotguns, which were marked with Dakin Arms Co., San Francisco. The Antonio Zoli marks were on the barrel flats and the water table. I have a boxlock 20 gauge sxs, 26", selective single trigger, ejctors, pistol grip, beavertail forearm, vent rib model. If I recall correctly, it was a Dakin Arms model 160.

The early 60s Gun Digests have a breakdown of the Dakin models in the European Shotguns index. Not all are photographed. If you can provide a comprehensive description of the shotgun, I'll try to pin the Dakin model number down for you.
