This mortar round is totally non-functional and inert, having been deactivated according to specifications outlined by the BATF (Bureau of Alcohol, Tobacco, Firearms and Explosives). It is totally inert, cannot be converted to an explosive device and is\u003cstrong\u003e not available for export.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a very good condition, rare example of the Japanese Type 100 HE Mortar Round used with the Type 97 (1937) and later the Type 99 small trench mortar. 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 with an impact fuse, though it is not currently removable. The bottom fins \/ propellant charge is also not able to be removed. It still has the original black paint with a yellow stripe, though the original markings are a bit faint.\u003c\/p\u003e\n\u003cp\u003eThe stenciled text one one side reads (with translations):\u003cbr\u003eLeft column:\u003cbr\u003e\u003cstrong\u003e100 式 \u003c\/strong\u003e- 100 Shiki (Type \/ Model)\u003cbr\u003eRight column:\u003cbr\u003e\u003cstrong\u003e九 七 曲 歩 -\u003c\/strong\u003e Kyuu Nana Kyoku Ho (97 Infantry Mortar)\u003c\/p\u003e\n\u003cp\u003eKyoku Ho is the abbreviation of \"Kyokusha Hoheiho\", which the IJA called the infantry mortar. It has another stencil indicating the weight specification. There are 5 possible markings for this: \u003cstrong\u003e++ + +\/- - -- + as this example is marked indicates 0.5 - 1.5% over weight\u003c\/strong\u003e while ++ 1.5% to 2.5% over, and -- 1.5% to 2.5% under.\u003c\/p\u003e\n\u003cp\u003eEvidently this was to make up for variations in manufacturing variables. These weight indicators would be taken into account when aiming, to obtain the desired ballistics.\u003cbr\u003eThere is also a faint arsenal marking on the body of the round, which is a faded date after that:\u003cstrong\u003e 六 十 昭.\u003c\/strong\u003e This marking is written right to left, and would be read: SHOWA (current reigning emperor) Juu-Roku Nen (16th year of reign - 1941). There may be additional markings, but they are unfortunately obscured by the paint or worn away.\u003c\/p\u003e\n\u003cp\u003eThe fuse is also marked with \u003cstrong data-mce-fragment=\"1\"\u003e八 八\u003c\/strong\u003e \u003cstrong data-mce-fragment=\"1\"\u003e式\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e, indicating that is a Type 88 Fuze, and there is even a date on the fuse, \u003cstrong\u003e5 四 十 昭\u003c\/strong\u003e, for May 1939 (Showa 14). 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.
