When was My Vintage Mixmaster Manufactured?

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.

But you can get a rough idea how old your mixer is from the following list:

In the early 1970's Mixmasters were drastically reengineered, and we scoffed when we first saw them, as they used plastic in their design. However, time has proven these to be tough, long-lasting  mixers, too. Models like the MMA, MMB, 1-7A, 1-8B, 1-8AT, and a few others were built during the 70's, and many of them are still in service today.

Affectionately referred to as "Plastic-Masters", one of their identifying features is their removable electrical cord, which unplugs from the right side of the motor body.

I know little about the very early (3 and older) models, as most of my repair work over the last 40 years has been on models 5 through 12, with some 70's models thrown in. But until they began sourcing their products offshore, Sunbeam built solid mixers. And up until the 70's models, Mixmasters have always been designed to be repaired and overhauled nearly indefinitely, so we still don't know how long one will actually last! 

I hope this page is helpful to you. Please feel free to drop me an email any time with any questions, and I'll do my best to answer them.
