One of the FilterFlo/RimFlo washers my Papaw had was an RCA. It was quite some years ago when I was really young so I'm not sure of many details about it. I know it was pretty straight forward though, three water temps, three load sizes, and I think just a Regulars and a Delicates cycle. It was white, panel and all, with the pull-ring style timer knob. Other than that it was all completely GE RimFlo design. I remember thinking it funny that they also had an RCA TV and wondering how one company could make electronics and washing machines at the same time, but I was too young to understand who actually made it or why a GE and other brand washer would look exactly the same.
