Japanese f headstamp

Hi guys,

GREAT to see this take off so nicely!

Thanks for sharing the info!

I've not yet shifted through my docs to compile a list of what I have, but there are some great titles there too. Also, I've downloaded a very extensive set of scans from microfilm on the USN reports about their mission to Japan. Some of it are rough and rudimentary, others contain interesting additions.
Most are not about ammunition, but other things.
Would ALL of those be of interest, or only the ammunition/weapons related ones?

Then, regarding Kirkee, I have scans of some 150 pages (pink paper ones) on ammo, incl. 20mm, 50mm, 70mm, 88mm, etc. It's a common digital title, yet people may not have it, so I can make that available too (as well as some more great titles, like NavSea OP 1667, a Japanese detailed document on ammo, etc.).

To be continued....

Cheers,
Olafo

WOW..... Personally I think that would be great!!!

I am into Ammunition and Ordnance and anything Japanese is most welcome.

Thanks to all that have shared (and are continuing to share) the wealth of knowledge and documents they have collected :tinysmile_fatgrin_t

How about the Hotchkiss 37mm

These have some marks but seem to indicate inspection & Navy ? So could be French manufacture - but there seems to be no information on this size in Japanese service. Use would be the Revolving Cannon. E.O.C. is the Elswick Ordnance Company who made Hotchkiss products under license and would have perhaps acted as the British sales arm of Hotchkiss.

Hi,
Cool items!
Yes, I have a 47x130R APHE round that was manufactured by EOC for the IJN. EOC was definitely one of the manufacturers fullfilling that contract. I have also read that indeed the IJN used the 37mm Hotchkisses, but I've got little information on it.
Regarding the anchor style on the driving band: that's the very same style anchor as is present on my EOC manufactured 47x130R projectile. It doesn't match any of the IJN (known, at least) arsenal marks. It's my theory that this style of anchor would have been used on ammo of foreign manufacture, that was destined for the IJN. However, until substantiated, I cannot be sure about that.

Cheers!

To bring us back a bit to the original topic of this thread, I have an interesting update. Previously I wrote:

It certainly hasn't been seen by me on any IJN case, and only (and always?) seems to appear on the typical style IJA headstamps, as shown in the original question.


Well then, with the addition of a Meiji era case, with otherwise pretty normal style IJA headstamp (Osaka manufactured in (September?) 1904), I can now at least say that the 'always?' part of my assumption is not correct, or at least not for non-Showa cases. Clearly the Meiji case I have has no 'F' anywhere on it!
I wonder when the 'F' was introduced, and/or if indeed it could mean 'full charge' with this case perhaps having been a semi-fixed case, with less than a full charge!

I'd be very interested to find out what this 'F' means indeed, and I'd also be very interested in seeing other non-Showa headstamps of big calibre ammo. Does anyone have any cases with Meiji or Taisho headstamps?

Cheers,
Olafo

Japanese docs from Kirkee 'Indian army'

Hi all,

At present I'm on holiday in sunny Venezuela, but I'v got a few moments time to fullfill part of my contribution to the docs on Japanese ammo.
Over the past few weeks, my co-webmaster of the NVBMB and ECRA sites, Charles Raam, has done an excellent job in adding a great many docs from Kirkee to the 'digital library', that's hosted on the NVBMB site.
Being the webmaster there, I can directly hotlink to them, without issues of server providers etc., as the owner of the server is your's truly. ;)
Nonetheless, it would be good if traffic could be limited, and if someone can perhaps add them to a specialised download server, such as is used for the previously posted docs, such that the load on my machine doesn't become too heavy.
Also, quite possibly there are duplicates between these ones, and the ones posted previously, but that's just a matter of filtering out the ones that weren't present already.

Enjoy!
Olafo

Since this seems to be the thread where the Jap collectors hang out, does anyone have any information of a 120mm or 150mm Japanese Short Mortar?

I have had a bizarre Japanese 150mm mortar projectile for over 15 years that has no tail boom, the fins are welded to the body. It is an original piece, but extremely hard to find a reference on. To date I have found it referenced only in a photo (poor) in one of the Navy technical mission documents, and in a partial document on the short mortars (3-4 pages of ?) we found a photo attached with this document, identical to my projectile, but cannot say for certain that this is the projectile referred to in the document. During a week long search for Japanese ordnance info/photos at the US National Archive I found a photo from Sasebo Arsenal with two of them in an open crate - but no info.

I''m at work right now, I'll attach a photo when I get home this evening
 
Here is the 150mm mortar, I've included one beside some 81mm's and 90mm's for comparison. Any ideas?

Only thing I could find was this picture in a document of the REPORTS OF THE U. S. NAVAL TECHNICAL MISSION TO JAPAN document O-19.
This can be found at this site.
http://www.fischer-tropsch.org/ Go to primary documents, then goverment documents. then to U.S. Naval Technical Mission to Japan ( or click this link directly if it works).
Here are some more ordnance related documents for download here.
There is only a picture of the 15 cm mortar projectile here but it is not mentioned in the text.
See you soon.
Regards Blu.

Thanks BLU- that is the same reference I mentioned in the earlier post. Other than that the only thing I've found is the photo from Sasebo - Nothing in my US, UK, Australian or Japanese references, and nothing has shown up similar in China either. Thought I'd bring it up on the off chance.....
