Tow Motor is a brand name and an early maker of the FL.
Kind of like Coke or Kleenex or Duct Tape or Channel Lock or SawZall.
Ah, I see. Not insulting people who call it that but it's strange to me lol. Just like midwest people mostly call it pop, but city folk call it soda.
Here in STL I have NEVER heard it called Pop,ever.
Upper Midwest for sure though.
