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.

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.

Mk.II  WWII 1944-1945
In the closing years of WWII the Mark II was produced with a solid base with the M10A3, or M6 series fuze (depending on the explosive filler used). The yellow band around the neck of the body was standard.

The are numerous variations in the fragment and groove details that can be found, which seems to depend on the particular manufacturer.

This grenade was originally made as an inert practice round, with a hole in the bottom and a practice fuse, which has the correct WWII style spoon. It was painted blue post war, the standard color the U.S. Army paints inert ordnance such as grenades, mines, etc. The fuse spoon is correctly marked M10A3, which is the version of practice fuse used. The bottom of the grenade has a cork in it, with some glue, so we believe it was used as part of a static display at one point.
