Tarawa. Japanese machine gun casings?


#1

The exploded casing was found inside the Japanese command bunker on Betio. A large concrete structure that to this day remains largely intact. My assumption is that the bunker was also an ammunition store - that exploded when hit by flame throwers. The in tact casing was found nearby.
It looks to me like a heavy duty machine gun casing.
Anyone have any ideas?
Cheers

Image provides no idea of scale, but the threaded primer pocket suggests it’s a naval 25 m/m Hotchkiss case; deformed one probably the same. Jack

Hi Jack, the rim is 43mm and the length 165mm. Does this fit with the Hotchkiss?
Cheers

Correct dimensions for the type 96 Navy AA gun (Hotchkiss) as Jack suggested.

Thanks for the advice. I understand that the Hotchkiss were US made?


#7

The Hotchkiss was a French design adopted by the Japanese navy and made in Japan for them. The origins of the Hotchkiss firm are American, but it was located in France, well known as a maker of arms, large and small (relatively), and automobiles. Jack

Thanks Jack, that clears things up. Great to be able to label these pieces - I’ve had them for nearly 25 years!

Cheers

Here are a couple of 1945 British technical reports on 25mm ammunition:
