This is a great example of the M21 Practice Training grenade, and inert version 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.
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. The Mk II was identified with an all yellow body prior to 1943. They were then painted olive drab for camouflage purposes with a narrow yellow band below the fuse. The are numerous variations in the fragment and groove details that can be found, which seems to depend on the particular manufacturer.
Igniter- M10A3. In 1943 this designation was adopted to differentiate this model with the M10A3 fuze from the grenades with earlier fuzes. Declared limited standard on 6 April 1944 with the adoption of the Grenade, Hand, Fragmentation, TNT, Mk. II.
This very nice WWII issue training grenade still retains the correct blue paint, and even has dirt still present in places from when it was used during practice drills. It comes with an original M10A3 fuse and pin, with the correct WWII style spoon. It is offered in very good condition. It has an open hollow end, as most practice grenades usually did.
It is contained in the correct HAND GRENADE MK II / CONTAINER M41 canister, which is marked on the bottom with PRACT. M21 to indicate the type of grenade it contains. The side of the bottom portion of the canister also indicates it contains 1-PRACTICE HAND GRENADE, M21, and that it was LOADED 8-44. The top of the container is from a later M41A1 canister, but still fits fine.
A great example of a U.S. WWII Practice Trainer Grenade, complete with the correct canister. Ready to display!
