About this 3D model

Add heavy firepower to your collection with this detailed 3D printable model of the legendary M53 self propelled gun and M55 self propelled howitzer. Developed in the early 1950s, the M53 (155mm gun) and M55 (203mm howitzer) were powerful U.S. self-propelled artillery vehicles built on a shared tracked chassis.
