The M1 75mm pack howitzer was designed in the 1920s to provide artillery support that could be moved across difficult terrain. The gun and carriage could be broken down into several pieces for carriage by pack animals, and saw combat in WW2 with the US Army (primarily airborne) and US Marines. Relatively small numbers were produced until late 1940, when a version the M8 carriage was introduced for airborne forces and jeep towing, incorporating pneumatic wheels. This version is featured in this product.

Two versions are provided, as the gun could be assembled for firing or with the axles in a different position and the barrel assembly retracted to improve towing characteristics on longer moves. Variants of each are provided to suit different printing technologies. At this scale, fully integrated versions should print acceptably on both FDM and resin printers. Versions with and without wheels are provided to suit user preference.
This design is based on the 1:56 offering, but changes have been made to make features printable, and to strengthen elements of the model for printing at this scale.
