Original Item: Only One Available. 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 devise.

This 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.

The 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, due to the fuse having been drilled through. Both the top cap and the fuse are removable for inspection, and both are reverse threaded, as is correct.

The original paint markings on the round are unfortunately completely removed by cleaning and age. The markings stamped into the round are still present, and there is an arsenal marking on the body of the round, which is dated after that: 11 九 十 昭. This marking is written right to left, and would be read: SHOWA (current reigning emperor) Juu-Hachi Nen (19th year of reign - 1944), probably the eleventh month of November. The first character is somewhat mis-struck, so it could also be 六, which would make the date 1941.

The fuse is also marked with 八 八 式, indicating that is a Type 88 Fuze, and there is even a date on the fuse, 4 七 十 昭, for April 1942 (Showa 17). The parts were made separately, and not assembled until they were issued, so having different dates is normal.

This piece would make a great addition to any WWII Ordnance collection. Ready to display!
