Different theory.......
I'm speculating there was still a demand for pans for woodstoves long after electric became available. It took a long time for electricity to reach rural areas. I'm guessing it was around 1952-3, when REA ran the lines on our farm. I remember Mama cooking on her woodstove. The new electric was sitting in the kitchen, covered with a pink bedspread, just waiting for power.
An older lady who lived nearby never converted from wood to an electric stove, even though she used electricity for lighting, ironing, etc.
Again, just speculating....
