70MM JAPANESE TYPE 92 Infantry gun cartridge

Up for your consideration and comments is my Japanese type 92 Infantry?? round. I did a search and found some comments and it seemed no one had a photo of the entire round. See inclosed Photos. It is pictured next to a 30-06 round for comparison. Also note that it had empty powder bags. I am very unfamiliar with this. Can anyone give any insight into the markings, or history, or any information would be appreciated.

I can’t add any info. But NICE! I like it!


I believe these are for the Type 92 7cm (70mm) infantry gun (howitzer) not a mortar. I have corrected the thread title accordingly. Beyond that I cannot help much.

The powder charge increment pads are pretty neat.

Hey 30-30

Here’s a pamphlet from WW2 that pretty much covers it. And please note, 1st page header, THIS LEAFLET MUST NOT FALL INTO ENEMY HANDS. So keep all this info to yourself. Don’t let anybody else see it.

Rick, it blows my mind that you have so much detailed info on a Japanese round! (Note that not much powder would be required to create that explosive occurance.)

And the powder bags… EMPTY… and so pristine! What a piece.

I don’t even collect stuff like that but its still neat to see.

Hey Shot

You ain’t seen nothin’! Got a HUGE friend in Oz land downloading a ton of those manuals on just about everything Japan had to offer in WW2. Have gone thru 3 ink cartridges and not even close to done. Am assembling them into a fine printed collection. Sadly, the copies of copies aren’t as good as I’d like(that MULTIPLICITY thing kicking in), but worth the effort. Will have an awesome reference when it’s all said and done.


I find it interesting to note that it was so important to keep this English intel manual safe from the enemy hands that already had the weapons, not to mention their own manuals?!?!?!?


Note also that the manual was from India and dated late 1945.

I laughed when I first saw that. Guess they didn’t want them to know that we knew what they knew. And most of these are dated early and mid '45. So a little late to the game, when it was all said and done.

And just so you know what all is included in this, there are nearly 300 of these little pamphlets. SAA will be loaded after he gets done with all the big stuff. Can’t wait!

And here’s how it’s all gonna look:

The tabs reference the pamphlet number, which is cross-referenced to a 7 page Index. There are pamphlets(numbered) and leaflets(A-J w/numerous titles) and near book long sections. Gonna go broke buying ink cartridges.

And disregard the grenade manual, that’s a WHOLE other project. Just know it was sent to me by the author after acquiring the 2 other, signed, in print volumes.


Really nice item.


Fantastic info on that round and looks like you’ll be the source for all things Japanese!

In thinking of the early to mid-'45 dates on the material vs. VJ-Day, it may be that such info would’ve been very important towards the final push on the Japanese home land. Massive amounts of planning were in the works towards that end without the knowledge of the devices that ultimately ended the war in the Pacific. We had a new enemy by late 1945 so there may be an entirely different purpose to the reports and secrecy of info from that time frame. Regardless, great info for collectors!

Rick, so are these manuals all available in the internet?


Sent you a PM regarding access.



Just a historical footnote, I got this at an auction, from a veterans estate. This man actually had a folding US cap from the USS ARIZONA. That cap went for $325.00. I think that after viewing this mans estate items I now know why Japan surrendered. This man had stolen the Japanese army. The ammount of items he possesed was staggering. From toothbrushes to postcards to guns, swords, and munitions. Wish I could have afforded them all.

I won’t question the authenticity of that veteran’s estate but I’d be very cautious about items with USS Arizona connections. That’s one WWII ship that most people are aware of and the fakers take advantage of it.

Earlier this month I was in a casino in Nevada and I spotted an old guy with a USS Arizona cap. I chased him down to shake his hand and talk to him, and commented on the cap. He told me that he had bought it several years earlier, new, and it had become well worn over the years. He had not been on the Arizona but he was a WWII Navy vet and wore the cap out of remembrance. When that old guy dies that cap may very well make it onto the antiques circuit and fetch a good price.

It is possible to buy military uniform stuff that is new made with just about any logo you want to have embroidered on it. I remember having things like that made when I was still in the Navy. You could find a tailor shop in most any foreign port that would do it while you waited.

BTW, what’s a “folding cap”? Do you mean a flat hat or pie hat?



That 75MM shrapnel fuze I mentioned in an earlier post? The one made by Paul Revere? It was fired from the Arizona. They used a sabot. Shot down Yamamoto’s plane with it. In case you were interested in acquiring it.


Ray since I was never in the military I dont know the difference. It was the type that folded flat and was often folded in half and tucked between the belt and pants. As for all the sceptics out their, I never said he was on the Arizona however he was in the navy as all his uniforms were naval. And all the other items I bought are original as were all the items I saw. I got a type 89 50mm mortar round, a sword (im a knife collector also) a type 97 grenade and a completely original type 99 rifle with all matching numbers, that included monopod, muzzlecap,sling, dustcover, and mum intact. By the way there were 343 survivors of the USS Arizona. That averages 6.68 per state.

As I said, I’m not questioning the authenticity of the items belonging to that old sailor.

That sounds like a “white hat”. AFAIK white hats did not have any markings that would indicate any particular ship. Flat hats were so marked but that practice was halted at least a year prior to Pearl Harbor. But, that doesn’t preclude an old salt from having one from the pre-war Arizona.

Flat hats were phased out of service in 1963, a sad date for the Navy. They were a girl-magnet, almost as good as pogey-bait.
