The chorehorse was built in 6, 12 and 24 volt versions over quite a few decades. There were commercial units built for the rural farm electrification programs in the Canadian prairies in 6 and 12 volt versions as well. These were identical in appearance to the military equivalents, but typically minus the metal guard assembly.
After the war, the Canadian military kept 12 volt radio systems in operation well into the 1960's, the last of it surplused out by 1970. At the same time, they were gradually introducing a vastly smaller quantity of vehicles and signals equipment based on 24 volt systems from the early 1950's onward.
It was probably just as cost effective to order a small quantity of new 24 volt units than have the older equipment reworked.
