The folks at Google need to stick their head in the Frigidaire and cool off.
We had a Kelvinator refrigerator, a Tappan range, a Westinghouse radio phonograph, and a GE television.
And a Kenmore window fan. Sears-Kenmore could have supplied all of the above, as well. Simpler times.
Anyway, when I wish to know, I consult _Mister_ Google.
