Crescent Fire Arms Company of Norwich,Ct existed fro 1892 to 1938 and perhaps later. It was owned by H & D Folsom Company of New York City from 1893 to 1930 when it was sold to a subsidiary of the Savage Arms Company called Savage Products Distributing who continued to make shotguns with the Crescent name. Folsom, a large wholesale and retail sporting goods dealer and gun jobber bought Crescent to supply it with inexpensive shotguns. And they did that very well making over 2,500,000 shotguns of all types using over 650 known "Trade Brand Names". Folsom claimed in their catalogs that they made the guns. Folsom did not have any manufacturing facilities other than the Crescent Plant in Norwich but I guess they could make that claim since they owned the factory. Most writers and researchers including my self credit all those names to Crescent AMERICAN GUN CO, AMERICAN GUN CO OF NEW YORK and AMERICAN GUN COMPANY OF N.Y. were names used by Folsom on guns they sold. I have no idea how they determined what name was used and when, on which gun.
