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. This is an M-21, which essentially is a MKII version made solely for training\/practice purposes in the later years of WWII and used into the 1960s. This example has a cork plug in the bottom hole.\u003c\/p\u003e\n\u003cp\u003eThe Grenade consists of an unmarked body, which still retains much of the original blue paint which indicated that the grenade was inert.

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.\u003c\/p\u003e\n\u003cp\u003eReady for further research and display!\u003cbr\u003e\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":42223478833221,"sku":"ONJR24HGMJ004","price":250.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONJR24HGMJ004__02.jpg?v=1737774919","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-korean-war-era-mkii-m21-inert-practice-pineapple-fragmentation-hand-grenade-with-m205a2-fuze","provider":"International Military Antiques","version":"1.0","type":"link"}
