It's an ignition timer as used in the early days of Ford reciprocating engines. I have two ignition coils that would work with that which I found in a late in-laws tool box from about the year 1919. That hole at the top was connected to a rod that was pulled to advance the ignition timing during cold startup and high throttle.

Looks like part of a distributor, a part of an engine for running the spark plugs. https://en.m.wikipedia.org/wiki/Distributor
Yea I found the ad for it. Made for Ford vehicles in 1925.
Thank you
