I don't think this Boyce Moto-Meter was for a specific type of
car.

My Orr Iron Company (of Evansville, Indiana) catalog has an illustration
that appears to match the item in question. The text states:

Midget Model Moto Meter............each $3 50
Notice: Special car name dials for use in the Midget Model Boyce Moto
Meters will be made only for the following cars: Chevrolet, Ford, Gray,
Overland and Star, and will incorporate only the trade-mark or name of car.
