Mixmaster Model 7
Above is the Canadian Mixmaster 7B with the Canadian logo. An older styling was used on the base compared with it's American counterparts.
Right is the Mixmaster 7B-1. Visual clues hint at something quite different here. Note the chrome juicer mount, two piece beater ejector and hidden latch pin. Since aluminum was diverted for the war effort, Sunbeam changed motor housing construction to steel and the gear box was cast iron.
