I also remember my appliance repair and parts store had some generic cords for older fryers and griddles, but that was in Mobile and was four years ago.
I like your fan. I have a couple of old table model fans also.
My father took good care of everything he ever bought. I have the original paper manuals for just about everything he left behind. My wife can’t believe it! I think he was very careful of where and how he spent his money. His cars and trucks lasted forever. I have all his tools - old Sears Craftsman stuff and good quality. He would not throw anything out that could be repaired by him or a local repair guy.
