Bit of history in those abbrvs.  The ABC ad says 'division of AMC' and dates itself 1960.  Where was Kelvinator?  When did the Altorfers bail out?  A quick summary of this swaparound would be interesting if one had a few mins to tap it out, thanks.

The Altorfers sold the ABC washer design to American Motors/Kelvinator in something like 1953 or 1954, IIRC.  There were still ABC machines offered along with Kelvinator-badged models for quite some time.  I don't recall exactly, but I think the ABC models were built in Peoria, Illinois until something like 1957 or 1958.  American Motors dropped the ABC brand in 1960 and just offered Kelvinator washers and dryers. 

This is by no means complete, but I am sure that others will have the 'fill-in' information. 

Thanks y'all.  About as clear as corporate genealogy gets.  Hey, ABC made spindryers!  Nice sturdy ones, looks like. 

Spent hours 'helping' grandma with the Easy clutch handles.  Seemed she and the machine got along famously.  There is a feel/knack for loading the spincan evenly.  I might have inherited it.  Seldom got a banga-banga with the Panasonic or even the flimsy Panda.  But then, I'm no housewife.
