Invented by Charles A. Feltman, grandson of Charles Feltman, who many cite as the inventor of the hot dog, these air guns were designed for use in "shoot out the star" carnival games. There is a plaque on the left side marked "FELTMAN PNEUMATIC/MACHINE GUN" above the Feltman Products Coney Island, New York address. It is patterned after a Thompson submachine gun with a threaded connection for an air hose at the bottom, wood grip panels, and a wood stock. These fire .150 BB's (#2 shot). Mechanically untested.
