Original U.S. WWII MkII M21 Inert Practice Pineapple Fragmentation Hand Grenade
Original Item: Only One Available. Totally inert and demilitarized according to BATF guidelines with hollow body and inert fuse. This grenade cannot be converted to an explosive device and is not available for export.
This is a nice inert practice example of the iconic U.S. fragmentation pineapple grenade issued during WWII. The Mk II was standardized in 1920 replacing the Mk I of 1917. It was phased out gradually, the U.S. Navy being the last users, and on 2 April 1945 the Mk II and Mk IIA1 were re-designated the Mk 2 and Mk 2A1. This is an M-21, which essentially is a MKII version made solely for training/practice purposes in the later years of WWII and used into the 1960s..
The Grenade consists of an RFX marked body, which still retains some of the original blue paint which indicated that the grenade was inert. Fitted to the Grenade is a correct WWII M10A3 fuze which is complete with original spoon, pin and ring. The Grenade is a RFX marked grenade, being an original with a stamped “RFX” as opposed to the commonly encountered reproductions which feature cast RFX markings. The markings stand for Richmond Foundry which was a known maker of the M21 practice grenade.
The Mk II was commonly known as a “pineapple” grenade, because of its shape and structure. Grooves were cast into the cast iron shell, which was believed at the time to aid in fragmentation and had the side benefit of aiding in gripping the grenade: this provision gave it the appearance of a pineapple fruit.
