When was My Vintage
I get asked this a lot, so hopefully the little chart
below might help answer that question, at least roughly. I understand
Sunbeam stopped stamping serial numbers on Mixmaster around 1956, and
records of the numbers on previous models were lost in a fire at the
Sunbeam plant anyway, or so the rumors go.

offshore, Sunbeam built solid mixers. And up until the 70's models,
Mixmasters have always been designed to be repaired and overhauled
