All those attachments...
I think it's a sign of the times that this mixer - and other products - came with so many attachments. My old Kirby vacuum also comes with a number of attachments. I'm thinking the trend was such for several reasons: good quality electric motors at the time were expensive and hard to come by. Also, the company could increase sales and profits by offering the customer these various attachments, many of which were not available as stand alone products. Nowadays, of course, nearly all those attachment functions can be obtained with stand-alone products that take up not much more space than the Sunbeam attachments must have taken.
My Kitchenaid mixer has an optional attachment I didn't see with the Sunbeam: a grain mill. I may be using it to make brown and white rice flours for wheat gluten free baking/cooking. There is also a pasta maker available with the Kitchenaid - which I didn't see for the Sunbeam.
