A surprising number of electric mixers manufactured in the 1950s or before are still purring on kitchen counters today, thanks to an enthusiastic group of collectors.

Restoration businesses have also emerged, as well as online marketplaces for salvaged and fabricated parts. A Yahoo news group called WACEM (We Actually Collect Electric Mixers!) has more than 1,800 members.

Collectors tend to focus on particular eras or makes, but most agree that a mixer generally isn’t worth having if it was made after 1967.

Mixers made later just don’t have the great design and are very hard to work on without destroying them, one collector said. If you take care of them, they will last forever, he added.

Vintage mixers ordinarily go for $20 to $300 on eBay, depending upon their condition. But rare attachments such as 1939 Sunbeam Mixmaster Model 5 bean slicer may go for $800.
