I am looking for information on the Canadian made .5 inch Vickers rounds.
All those I have seen were made at Three Rivers which I believe was run by the Dominion Rubber Munitions Co. According to the History of the Department of Munitions and Supply by Kennedy, semi-AP tracer and Incendiary were made.
The Woodin Lab has an excellent range of these rounds (as usual) some with the bullets completely coloured rather than just tipped. Are the red tipped rounds just tracer? There were no tracer rounds adopted for British service. Similarly there are blue red green tipped rounds suggesting APIT.
All the above are headstamped “44 TR”. This is quite late for the .5 Vickers but I am told these were for the Merchant Marine for AA defence. In a way this makes sense as by 1944 most warships had had their Vickers replaced by 20mm Oerlikon so Vickers mountings would have been freed for the Merchant service.
Any information appreciated.
