Totally inert according to BATF guidelines with a hollow body and inert fuse. This is a nice example of the M21 Practice Training grenade, an 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.\u003c\/p\u003e\n\u003cp\u003eThe 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. There are numerous variations in the fragment and groove details that can be found, which seems to depend on the particular manufacturer.\u003c\/p\u003e\n\u003cp\u003eThis nice WWII issue training grenade was repainted in an off-color yellow or white, with some chipped areas showing the original blue underneath. It comes with an original fuse and pin, with the correct WWII style spoon, but the marking on the fuse is too faint to discern its model. It is offered in good condition. It has a plugged end which was likely done when it was painted.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUnloaded or dummy grenades, artillery shell casings, and similar devices, which are cut or drilled in an BATF-approved manner so that they cannot be used as ammunition components for destructive devices, are not considered NFA weapons.
