I have a C&H brass (at least I think it's brass - see picture, assuming I uploaded them properly) handgun that appears to be a flare pistol. It has a spent shell casing in the chamber that looks like a large shotgun shell. I know nothing about the gun nor how old it is. Any advice on the gun? Date of manufacture? Value? It has a serial number of 72544, crudely imprinted on the gun, which makes me think it was mass produced at some time. Thanks for any info (or for even considering my post).
