Well, Frigidaire exclusively made that pulsator agitator, the jet-cone, the one going up & down, etc.
Kelvinator might have had similar success, only needing its own trademark name for their's...
The brand along with Gibson hardly made any impact, as by this time WCI-consolidated brands as even Frigidaire and soon to be WHITE-Westinghouse would do, let alone, the Norge-clones and leaders like Whirlpool, Maytag and GE...
Yes, DJ--typo's! Done a plenty myself, and while upgraded even, found too late to correct--would do in a succeeding post or hopefully (& hope now) something is natively clarified...
