did ford use a stewart model 12, 50 mph, on any of their cars?
It was an option on the 1909 Fords along with the Stewart Model 11, Jones Model 20 and Model 21 and the National speedometer. It was the last centrifugal speedometer Stewart produced. Hope this helps.
thank you russ
i see one in an antique shop that works and didn't know whether to buy or not.
