Years ago I got carnival bb machine gun that runs on compressed air. It’s like the “shoot the star” guns made by Feltman of Coney Island fame. This gun, while on the outside looks almost identical, the internal mechanism is different. The gun has a tag stating “Old Neck Industries inc pneumatic gun, Center Moriches N.Y.” trying to get it to work and I can not find any information on the web about it or the company. Any help would be appreciated.
