Re: Timing gears
Celeron was a process/material developed by General Electric where canvas or linnen fabric was impregnated with phenolic resin. These 'prepegs" could be compression molded around a metal hub and then machined. Phenolic resin is a thermoset and once cured by heat and pressure does not soften with further application of heat. Westinghouse developed a similar product with the trade name Micarta.
No doubt these processes were licensed to Ford for timing gears or GE supplied parts to Ford.
