Original U.S. Pre-WWII Inert MkII Pineapple Fragmentation Grenade w/ “Cutback” Fuze

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 before and into the early days of 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. Early MKII Grenades features a “cutback” style fuze, and a more taped body which was tapped for a screw on the end. The Grenade still retains its original Grey paint, which indicated that the grenade was “loaded” during the WWI-Pre WWII period.

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

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 filling is 0.74 ounces of EC Blank fire powder.

This great WWII issue grenade unfortunately has no original green paint or the yellow ring painted at the top. The grenade body is the type with a solid bottom, and still stands on end. It comes with an original fuse and pin, with the correct WWII style spoon and sealing washer.

A very nice example of a deactivated U.S. WWII Grenade, ready to display!
