Authentic WWII Japanese Type 89 50mm Mortar Round — Inert / Demilitarized
This is an authentic WWII Japanese Type 89 50mm mortar round (commonly associated with the infantry “knee mortar”), offered here as an inert / demilitarized display example. The Type 89 was the standard light mortar used by Japanese forces in the Pacific theater, prized for its portability and rapid deployment at the squad level.
The round retains its original wartime configuration and surface finish, including visible casting marks and stamping typical of Japanese ordnance production. The body shows age-appropriate patina and handling marks; the baseplate exhibits the expected wear from long-term storage and display. this example contains no explosive filler, no functioning fuze components, and is intended solely for study and display.
This piece is suitable for museum exhibits, educational displays, or serious militaria collections that document infantry weapons and munitions technology from World War II. It provides tangible context for the Type 89’s role in light mortar tactics and small-unit operations.
