As Tom said,
While US sets were marketed as RCA Whirlpool, they were not made by RCA.
But
The Canadian RCA Victor and RCA Whirlpool were made by Inglis for RCA, using many Whirlpool parts and patents.
In fact, when Whirlpool stopped using the RCA name in the US, the Canadian version went the other way as they stopped using Whirlpool. So they were briefly badged as RCA Victor and then just RCA. Then in the early 1970s, RCA Canada changed it's line from being Made by Inglis/Whirlpool to Westinghouse. And I have documentation that shows they switched again to GE around 1977 as I saw a 1977 RCA document showing a GE/Hotpoint washer.[this post was last edited: 12/17/2016-07:17]
