This is based on the Stokes-Brandt design, as was the U.S. 81mm, and this round was actually interchangeable with the U.S. M43A1 shell.\u003c\/p\u003e\n\u003cp\u003eThe Japanese Type 100 round had a maximum range of about 3,000 yards. Loaded weight: ~3kg (6.9lbs) of which 1 pound was TNT. This round is complete, except that the detonator tip is missing. The top cap is also not currently removable. It still has the original paint markings indicating type and other information regarding the round.\u003c\/p\u003e\n\u003cp\u003eThe stenciled text translates-\u003cbr\u003eLeft column:\u003cbr\u003e\u003cem\u003e\u003cstrong\u003e100 Type (Model)\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003eRight column:\u003cbr\u003e\u003cem\u003e\u003cstrong\u003e97 Infantry Mortar\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eKyoku Ho is the abbreviation of \"Kyokusha Hoheiho\", which the IJA called the infantry mortar.

This marking is written right to left, and would be read: SHOWA (current reigning emperor) Juu-Nana Nen (17th year of reign - 1942), probably the fist month of January. The marking on the base reads \u003cstrong\u003e12 六 十 昭\u003c\/strong\u003e, for December of the previous year, 1941 (Showa 16). There is even a date on the fuse, \u003cstrong\u003e八 十 昭\u003c\/strong\u003e, for 1943 (Showa 18). The parts were made separately, and not assembled until they were issued, so having different dates is normal.\u003c\/p\u003e\n\u003cp\u003eThis piece would make a great addition to any WWII Ordnance collection.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":31253725118533,"sku":"ONSV5447","price":395.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/products\/ONSV5447__03.jpg?v=1594941677","url":"https:\/\/www.ima-usa.com\/products\/original-japanese-wwii-type-100-he-81mm-inert-mortar-round-dated-1941-1942","provider":"International Military Antiques","version":"1.0","type":"link"}
