I purchased a bag containing 76 rounds of .303 at a local gun show today. Most of it was WWI and WWII surplus:

Dominion Arsenal (DA) 1911 VI
Dominion Cartridge Co (DC) 1915 VII
Dominion Cartridge Co (DC) 1916 VII
Dominion Cartridge (DAC) 1917 VII
Dominion Cartridge (DAC) 1942 VII
Birmingham Metals & Munitions Co (J) 1916 VII
South African Mint (U) 1941 VII
Winchester (WRA) 1941 VII
Winchester (WRA) 1942 VII
Winchester (WRA) 1943 VII
SAAF No2 (MG) 1944 VII

There was one round that I was unable to identify the head stamp. I have attached a picture of the head stamp hoping that somebody will be able to educate me.
