Henry Ford also had a charcoal business (Kingsford) to use up all the odd pieces of wood cut from boards used in car construction at the time. I think there was a Kingsford who ran it, who was some relative of Henry. What wooden crates and boxes he couldn't use for floorboards or making Woodies probably ended up in a Kingsford charcoal oven. Charcoal was sold through Ford dealers. I remember seeing bags of charcoal sitting in dealer showrooms back in my youth.
