We have a new contender for the top spot in my early automotive tool collection! This tool reads, "E.M.F-CO, DETRIOT, A-1308-01".
Everitt - Metzger - Flanders Company produced automobiles from 1909 to 1912, at one point being second only to Ford in production. EMF was bought out by Studebaker, and the EMF model 30 was rebadged the Studebaker model 30 in 1912. These rebadged models continued through the end of 1912 when the EMF name was dropped. Interesting automotive history of this short lived car company and the men who founded it.
And I don't think I overpaid for it.
