Japanese Projectiles and Fuzes. It is a Confidential publication compiled by US Navy Mobile Explosives Investigation Unit No 4 dated 19 January 1945.
I saw the 25mm cartridge in your gallery after I had started to take photos of fuzes in the book that matched your gallery fuzes, when I thought there are so many of these that he may already have these in modern format so I stopped until I found out whether these pictures were needed. You and others may already have these in a more modern publication.
I went as far as a powder filled fuze of the Meiji period, which I was interested to see was made by the Elswick Ordnance Company, England.
I included the Type 91 fuze here because I saw the red dome on one of your fuzes and although the title was not quite the same it looked very similar.
I still have all the fuzes that I put into my computer and if these are required I will send them them to you and anything else that applies.
I am unfamiliar with this site having only recently joined, I am a Mac user so the microsoft feel is different and I am a pre WW2 baby so my grandaughter knows more about computing than I do.
There is a Chinese Mortar fuze, a Navy 8" Rocket, plus a Rocket Motor for a 60 kg type 97 Navy GP Bomb, otherwise everything is as described in the title, including Mortars.
I could not see any way to put photos into your gallery so that is why I have done this thread. Perhaps this is the way to go about it so that any other Japanese ordnance collector scan share the info.
In the front of the book are 2 pages all the ordnance terms like Howitzer, AP, Mountain Gun, mm, pyrotechnic, etc., with the Japanese calligraphy associated with them. Some of it is not too clear particularly the fine lines and they were probably not drawn by a Japanese.
