There were shotguns stamped Keystone and Keystone Arms Co. made by W. H. Davenport Arms Co. They were distributed/retailed by E. K. Tryon Jr. & Co. of Phildelphia, Pa. My list shows a New Keystone Rapid Fire Steel as a Crescent single shot.

Yes, Crescent Firearms did produce 16-gauge shotguns, particularly during the early to mid-20th century. These shotguns were often part of their popular line of double-barrel and single-shot models. While they may not be as common today, collectors and enthusiasts may still find Crescent 16-gauge shotguns in the market.
