Was this a dealer supplied accessory?
Forgot the gear mechanism.
Yes, dealer accessory. Many types of odometers made to fit early cars. One use was for taxi, rental, or fleet vehicles, so that mileage could be recorded. Thereby knowing when to change oil or what miles to charge the customer!
Veeder was early mfg of these parts.
Another type, the hub cap styles came later, the one you have is nice period accessory made for the Ford.
