Loved the picture!
Reminded me of 1969 Consumers Reports article on washing machines with discussion of "agitators made from phenolic vs. polypropylene". Am I correct in assuming that phenolics are plastics derived from pine tar? Any relation to bakelite?
What are the properties of each material and what advantages in producing a washer agitator?
Also, I was always curious to note that the black plastic agitator on our GE WA-750W(1962)dulled quickly to a matte dark gray whereas the seemingly identical black agitator on her GE WA-750X(1963) stayed black and shiny to the end of its days. Is it possible that one was one material and the other another?
I also vaguely remember a Maytag brochure from 1969 describing its "Power-fin agitator" being constructed of polypropylene. Were the earlier black ones also?
