Japanese Type 89 ACMG

Did the Type 89 ACMG in 7.7mm X 57mm SR caliber get used by the Japanese Navy aircraft or was this gun & caliber only used by Japanese Army air craft?

You may find the answer in this if you can find a copy. I have one but it is all JPG files and needs collating.

Scrub that - it is all army stuff - nothing aviation

I will check my Indian Air Force docs when I get a chance

Great info, thank you, but still no definitive answer. I am coming to the conclusion that both Army & Navy were very strict about keeping their guns & ammunition seperate from each other! No where have I found where type 89 guns firing 7.7mm X 57mm SR ammunition were used by the Japanese Navy. Regards Ozzi.

On an unrelated note: can anyone please post a picture of the IJN's 100-rd drum for the 20mm aerial cannon? Seems pretty illusive...

This Type99 20mm MG at the Yasukuni Shrine is said equipped with the 100rd drum.

It's like almost like being able ask Jiro Horikoshi's office directly for information with Shinpachi here.

Thank you, yes I am aware that both guns & ammunition are not interchangeable.
