Anyone know what "Sheffield # 20" means? I picked this up today at a gunshow. I will try to post pics later. It's a 4" Commando serial # 3495. Thanks
There was a defense contractor named the Sheffield Corporation in Dayton, Ohio, that manufactured precision gauges used to check manufactured parts for interchangability.A good possibility that it was a revolver supplied through the DSC, and marked with the facility and weapon number where it was sent.
