The MODEL M was built only as a delivery vehicle.
It was the same as the 1907 delivery except that prices now included two oil side
lamps, an oil tail lamp, and a bulb horn. Headlamps were not included as standard
equipment on Cadillacs until 1910. Also it did not have the longer wheelbase or
running boards found on the Model S or Model T.
I. D. DATA
- On the models M, S & T, different combinations of 9 or 10 tooth driving sprocket with 31,
34, 38, 41, or 45 tooth driven sprocket gave ten possible ratios from 3.1:1 to 5:1.
|| Driven Sprocket
|9 tooth drive sprocket
|10 tooth drive sprocket
- Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded
Delivery to be run on rough, hilly roads.
- Instructions for changing sprockets were available for owners, but the change involved
disassembly of the transmission and rear axle -- definitely not a "quick-change" set-up.
