Manufactured circa 1958-1962, the Dardick 1500 uses a novel combination of a fixed in-grip magazine, an open-sided auto-ejecting three chamber cylinder and a proprietary plastic-cased triangular cartridge dubbed the "tround". This combination permits an ammunition capacity inline with an automatic pistol while retaining the simple reliability of a revolver. Additionally, the barrel is secured with a single threaded bolt and can be rapidly detached or swapped. Includes a desirable 21 inch barreled full-stocked .22 caliber rifle conversion unit with it's own unnumbered factory long box. Also includes an unnumbered blue factory pistol box, an extra 4 inch .38 barrel, two Dardick sales brochures, a 100-round "brick" of five full Dardick .38 tround boxes, and two loose boxes for a total of 126 live trounds and 3 deactivated trounds in total.
