M-19 GMC (40mm AA) on Chaffee chassis

The M19 Twin 40mm Gun Motor Carriage was an upgrade over the combat proven M15 halftrack series. The M19 full-track carriage featured two turret-mounted 40mm Bofors guns on an M24 Chaffee light tank chassis, but was not accepted by the Army until the war in Europe was all but over (285 built), so the carriage did not see significant employment until the postwar years and the conflict in Korea. The M19 carriage should not be confused with the later twin 40mm M42 Duster that was produced in the 1950s (see separate model).

Versions suitable for fdm and resin printing are offered, with a common (separate) turret. Solid and hollow hull/tracks are made available, and the fdm version offers separate hull and tracks to ease printing. Some of the turret components are quite fine, but appear to print satisfactorily when tested.

The product is offered for personal, non-commercial use. Derivative designs for personal use may be generated, but neither the original nor derivatives may be shared with others. Attribution of the design is requested should printed models be exhibited or otherwise shared. Models printed from this design or derivatives may not be sold commercially.
