<span style="font-family: courier new,courier;">With juicer attachement. Anyone know the year of manufacture and what color the bowl should be? </span>
a model 7b. It was the first Mixmaster to have the beater ejector. The black base gives it away. The model 5 had a painted base. They began manufature in April 1941. Production stopped during WW2 then started up in 1946. Over three millon were made. Looks like you may have the smaller citrus reamer (lemons, limes etc...)which is pretty hard to find IMOHO.
Sorry, folks, but that's a model 9! Speed 4 on the 5, 5b, 7 and 7B would have been for 'juicing citrus fruit' and this one is for 'whipping potatoes'. The bowl would have definitely been white, though.
Where's the strainer? The model 9 has a strainer that fits in the juicer bowl that shakes or "joggles" that is why the speed for juicing was changed with the model 9 mixer. This also the first Sunbeam model to feature the bowl speed button on the bottom of the beater that is closest to the side of the bowl. Hamilton Beach had the same feature starting with their model G stand mixer. HB did not advertise having this feature like Sunbeam.
