What recipes used for this plastic, assuming it is Tenite, varies greatly between one make and the next and one model and the next. The worst ones I have seen were used on Silvertone radios of the late 1930s, the best being used on RCA radios of the same time period. Even within Philco some items suffer more then others, the 8 pushbutton escutcheons used on the 41-280s were awful, sometimes they not only warp and crack but turn black and begin to disintegrate. On the other hand dials on the mystery controls and the plastic covers over the phonograph pickups on the beam of light changers, while they warp a bit, I haven't seen one that is total junk as yet. I guess the escutcheons used on these 41-266Cs were maybe more resistant to decay then the light brown ones because of the dye or filler used, more U.V resistant perhaps?
