This quote from "blue Book of Gun Values".....

Crescent Firearms Co. remains best known as a manufacturer of "house brand" shotguns (i.e, Crescent private labeled guns for retailers, distributors, mail-order houses, etc.). Over 100 different trademarks have been observed to date, manufactured by Crescent - almost all of the remaining specimens today are priced as shooters and have no collector value".

Hope this helped......
