Hi ,
Looks like a Type 93 instantaneous short delay mortar fuse, appears to be missing the top striker part.
Can you post pics of the top of the fuse?

cheers
Bob

Found and doctored a couple of pics from manuals, painted lines indicate missing section.

Hi Bob,<br>
I don't think it is a type 93 Instantaneous -Short Delay . I already have one and this fuse is much smaller.<br>
I agree the top striker unit is missing. By the markings it is Army <br>
The overall diameter is 31.60 mm<br>
Length is 81.60 mm<br>
Thread diameter is 23.70 mm<br>
The gain is 10.95 mm dia.

Cheers

Hi ,
The measurements you give are very close to the Type 93.
Dia 1 1/4 " =31.75mm
full length 3 13/16" =96.74 (less the missing piece)
Also in my references is the only fuse with that distinctive shape magazine/gaine.

Have a look at Bougainville's gallery, hes got one in pieces.

cheers
Bob

Hi Bob,
You are quite right, it just goes to show that you can't rely only on one or two reference manuals and the forum is there to help.
Thank you for your help.
Cheers

Definitely a Type 93 - this fuse "stands out" even without the top bit.

Nice find with the shipping container - first one I have seen with this type of fuse ...............would probably have it marked if you de-cypher the Kanji.

Very nice find spitfire-01. It sure is a Type 93 Instantanious - Short Delay Fuze as used with the H.E. 81mm, 90mm and 150mm mortars and the Incendiary projectiles for the 90mm mortar.

So it looks like you are on the look out for the missing fuze head. The head screwed off in order to insert the delay pellet.

I might just know where you could score the missing part or parts.

Cheers,

Hi,

Fuze ID is correct. Definitely a Type 93 mortar fuze without the top part. What I wanted to add: the lid of the fuze tin says "Type 100". It looks like it's either the wrong tin for the fuze (probably the tin was for the Type 100 mortar fuze), or perhaps the Type 93 fuzes at some point in time were also shipped in Type 100 tins. I'd guess the former, though.

Cheers,

Interesting observation Olafo as I did see the "0 0 -" also but it didn't "click" for the smaller Type 100 mortar fuse - (just getting older and more stupid!)

Now we know why the top of the Type 93 is missing - it wouldn't fit in the container eitherwise!

Cheers
