An unusual Japanese Artillery Fuze


#1

I recently came across a variant of the Type 88 Short Delay artillery fuze that I can find no documentation on.

The fuze in question is marked like a standard Japanese Type 88 Instantaneous. It is dated Showa 5.15 (May 1940).

When compared side by side to a standard Type 88 Instantaneous, you can see that it is considerably shorter, and has a different profile;

Also, looking at the bottom of a standard Type 88 it does not have the normal internal threads for the gaine, the external threads are shorter and finer, and there is a snap ring over the firing hole. It looks like maybe the gaine is supposed to have a snap on fit instead of being threaded?

Any information would be much appreciated!

Thanks,
Dave

Thanks a lot for clarifying this!

And before I am gonna die from curiosity, what book is this?


#6

The name of the book is 《弹药识别手册》(Handbook of ammunition identification).
The book is not mine, but a friend’s book.
The book was published in China.

This is the type 88 instantaneous fuze.

Thanks a lot!
Can you maybe tell how many pages it has and who the author is?
Does the book have an ISBN number?


#9

The book was published within government agencies in 1950. There is no record of its publication. The author and ISBN are unknown.
I have a soldier training textbook issued in 1987 by a Chinese government agency. It is also unknown to the author and ISBN.

Too bad, the book looks like a valuable source of information.
Does a digital version of this book exist?
