Kenmore Mixers
I hate to be the bearer of bad news,but the old Kenmores were built by Birtman electric company,they were bought out by Whirlpool in 56 or early 57,I read about this in consumer reports and I cant remember the exact date,Sears instigated this so several products would be under one management,since Birtman was a small company,and basically made all sears vac's as well as mixers,they were able to buy them out,Birtman made Bee-Vacs as well as mixers under there own name,I have seen one of these,I think H B did make the hand mixers,I am not sure what happened after the merger.
