I've always found Crescent to be in Norwich, CT. In my small stack of H&D Folsom catalogues, in No. 18 their cheap gun is called American Gun Co. and their primary sidelock hammerless gun is the No. 6 Knickerbocker. Catalogues No. 23 and higher show their cheap gun as Crescent Fire Arms Co. and their hammerless gun is the No. 6 "Peerless" (The Old "Knickerbocker" Improved). The parts lists in catalogues No. 23 and higher show "Finished Repair parts for Crescent or American Gun Co. Guns." By catalogue No. 31, dated 1929-30, the same picture of repair parts says for old models, and the parts for New Models shows a bent piece of wire "V-Spring" replaces the coil mainspring on the lockplates.
All these models are bolted by an underbolt and wedge off the top lever into a slot in the rib extension.
Revdoc,
Colton was a forerunner to Union up in Toledo, Ohio, and involved in another SR&Co. adventure to outfit a factory to assemble Spencer pump guns from the remnants Bannerman unloaded on them. As I recall one of Uncle Dan's boys went to work there after D.M. Lefever ceased to exist.
