"Crescent Firearms Co operated from the 1890s to the 1930s, then was absorbed by H.D. Folsum in 1893 and by J. Stevens Arms & Tool Company of Massachusetts in 1932. This gun was a low to medium-priced gun manufactured on a large scale."

"Crescent operated from 1893 to 1930. There doesn't seem to be any source to pinpoint dates of manufacture by serial numbers. Crescent was a subsidiary of H&D Folsom Sporting Goods, New York. Many of their products were sold through Folsom's retail outlets, but Folsom was also a large wholesale dealer and many Crescent guns were marked with the names or trademarks of other retail chains and even independent hardware stores."
