Odd WWII 9MM Ammo

What can anyone tell me about this?



My picture is not great but the headstamp is “DV 43 9MM” with three small triangles around the primer.
Thanks,
Kevin Williams

DI not DV, Defence Industries, a Canadian crown corporation which was a major manufacturer of 9mm, .303’" and other calibres 1941-5.

The packaging is standard for Canada for the times in which was made. I probably represents filling for two Sten Gun magazines. That packaging continued for some time after the war.

Thank you!
