Original Japanese WWII Type 100 HE 81mm Mortar Round

Item Description

Original Item: Only One Available. Totally non-functional and inert having been deactivated according to specifications outlined by the BATF (Bureau of Alcohol, Tobacco, Firearms and Explosives).

This is an excellent 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.

The stenciled text translates-
Left column:
100 Type (Model)
Right column:
97 Infantry Mortar

Kyoku Ho is the abbreviation of "Kyokusha Hoheiho", which the IJA called the infantry mortar.

Note: The "+" on the back side indicates it is 0.5 to 1.5 percent over standard weight.

There are 5 possible markings:
++   +    +/-    -     --    

 +/- as this example is marked indicates nominal weight, while ++  1.5% to 2.5% over, and -- 1.5% to 2.5% under.

Evidently 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.
