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 devise and is not available for export.

This very nice WWII issue grenade comes complete with a 1944 dated Rifle Grenade Adapter, marked on the side in yellow paint stampings:

ADAPTER, GRENADE
PROJECTION, M1
J. J. N. - 8
1944

This adapter allowed the MkII pineapple grenade to be used with the M7 and M8 grenade launchers for greater range. It is in very good condition, though the fin assembly at the bottom is dented inward on one side.

The grenade itself bears all original green with a yellow ring painted at the top, and comes with an original inert fuse. It is offered in very good condition, and the fuse still unscrews from the top, though it is missing the spoon and pin. This is the type of grenade without a bottom plug. There are also still visible maker markings on the side of the body.

Genuine examples with original paint are extremely hard to find on the market today, especially with the rifle grenade adapter! Ready to display!

The U.S. Mk II grenade was an 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, 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.

Pre-WWII high explosive-filled Mk 2s were painted bright yellow. During wartime (from about 1943 and after), yellow grenades were over-painted in olive drab, leaving a narrow yellow ring remaining at the top. Newly produced grenades were painted olive drab, and had a yellow ring added later. Not all were over-painted, however, as D-Day film footage shows.

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.
