T-100 Japanese Mortar Rounds

[Geoff Ward]

Hello all,Although I am not an ordinance collector I do have a few pieces I am happy to share.Although these rounds are usually found with a Type 88 impact fuse
The Type 100 instantaneous/time delay fuse is the correct fuse for this round.The type 88 will not arm until it is spun in a rifled barrel.Perhaps G.I.'s had more access to the T-88 or thought they were more impressive looking! In any case I think they make an interesting display!

Nice trio. I have one with the type 88 fuze and yellow band. Use it to display a US tankers helmet

Are you saying the type 88 is not correct?

From what I have been able to research the Type 88 was for artillery rounds and the fuse would arm itself with the centrifugal force caused by the spinning of a rifled barrel. This mortar tube was not rifled so the fuse did not receive the action necessary to activate.I cannot say for sure if it would detonate on impact.I have not yet been able to answer that question but the thoughts are there were many more of the type 88 fuses available so they were de-activated and sent home in this way.They definitely look more impressive than the Type 100! more info here Japanese Type 100 81mm Mortar Round - Inert-Ord.Net Great Website!
