6.5×52Carcano round and a 7.7×56R made in Japan，different from the 7.7×58R Japanese Type 92or99，this is an 7.7×56R/.303British made in Japan.Can’t believe this type of cartridge can be produced by Japanese，I can’t imagine what type of Japanese gun can use it…
The Japanese used machine guns that were chambered for the 303 British cartridge, copies of Lewis and Vickers drum fed aircraft machine guns.
Yes, the Japanese Navy manufactured ammo for said machine guns, your case is one of them.
Looks like the date is 19-12, that would be December 1944.
The 6.5x52mm Carcano was produced by Pyrotechnic of Bologna, Bologna, Italy in 1943 (B - 43).
The letters “T. R.” are the initials of the inspector.
E is Yokosuka Naval Arsenal. Easy for me to remember, Russian letter Ё is literally Yo. That firing pin depression must be a rarity, I think all my Japanese .303 Brits are unfired, with intact primers.
Love the way the cartridges are polished, they look like they were just made!
i never see new made cartriges polished as these above
“out of the boxes” they had particular color
i only see high polished cartridges for shows only
I think it is a corn husk tumbler in action.
I think 91-12 would be 1931 date.
The earliest date I had seen was E 7.7 95-12 (1935) until this photo was shown.
Here is an old topic which has a katakana chart (scroll down in that old topic) .303 IJN headstamps, it shows all these Japanese characters, with correct orientation. When we write “E”, it is actually " ꓱ".
Almost looks like a Bren gun primer strike
