No H.&D. Folsom Arms Co. nor Crescent Fire Arms Co. records survive, but Joe Vorisek estimated the following production 1897-1932 at more than
1,200,000 doubles:
Sidelock Hammerless (except Empire and Quail Model) - 450,000
Empire, New Empire and Quail Model Hammerless double - 120,000
Hammer Double (except small gauge) - 630,000
Small gauge hammer double - 40,000
Not too many are still shooting

Despite the condescension toward "Farm Implement Grade" U.S. doubles, most well used but not abused 00/Field Grade Smiths and Ithacas are still doing fine, with minor maintenance
