I looks like the part that came off my 1955 originally it was six volt positive ground. The PO went to twelve volt and used several voltage reducers on instruments , electric WS wiper and heater motor. All were burned up, AJ

It’s a sperving bearing from a turbo encabultor. If it’s real and not a repro it will be fabricated from prefamulited amulite. There’s an easy test, install it and look for side fumbling, if that’s effectively eliminated it’s good and can be reused.

that is a Finnagin pin regulator. it's purpose was to keep the Finnigan pin in the cigar lighter centered in the casing to prevent shorts.
if you do not reinstall it with the stock lighter socket, thee is a good change of electrical fire.
if using a modern lighter socket, it is not needed as they come with built in Finnigan pin regulators.

With a 55 I am guessing it's a fuse. I found something simuliar on the back of my lighter on my 56 but it was ceramic if I recall correctly and checking it with my ohmmeter it was open. Mine looked more like a dropping resistor which to me made sense as 56 was the first year of the 12 volt systems. My theory is Ford probably had who knows how many 6 volt cigarette lighters left over. It looked to be a wirewound resistor so it also could of doubled as a fuse since too much current draw from the lighter element could of burned the wire inside the ceramic resistor open. Mine was burnt and discolored for sure.

it is not, and you know it!!! the turbo encabulator was not invented until 1959. so it's parts could not be found on a 55 truck.
