My father had a plastics factory just after WWII. They used primarily Bakelite for radio cases, phones etc. That was in England. I believe that in the USA, Tenite was more common. It allowed more colour options. I think, if memory serves, Tenite was petroleum based while Bakelite was coal based plastic.
In 1945 in the UK, coal for home use got so scarce that we used to burn scrap bakelite in our fireplaces (no central heating). I remember it smelled terrible.
Sorry about the digression.
