Item Description

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 an excellent 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. 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.

The Mk.IIA1 could be found with either the earlier body with a filling hole or the newer body without filling hole. It was up to the manufacturer which body style was used. The grenade is fitted only with the M10A3 fuze mechanism. The filling is 0.74 ounces of EC Blank fire powder.

This very nice WWII issue grenade has been repainted post war with OD green, and comes with an original M10A3 fuse and pin. It is offered in very good condition. It even still has the bottom fill plug, painted in place. Genuine examples with an intact bottom plug are extremely hard to find on the market today. It is contained in the correct M41A1 canister, which is marked and dated on the side with the version number and a filling date of 4 - 45.

A great example of a deactivated U.S. WWII Grenade, complete with the correct canister. Ready to display!
