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. Featuring a rear-mounted open fighting compartment and massive artillery systems, these vehicles delivered long-range fire support with impressive destructive capability.

This model captures the large-caliber gun assembly, detailed suspension system, open rear crew compartment, and heavy tracked chassis — making it perfect for Cold War military collections and artillery-focused dioramas.
