Gonna watch this one! Pre '38, and the 100mph could also mean '31+ Scout but just guessing here!

I would say this is mid to late 1920ies Indian. In 1934 the internal lighting was introduced. Typically an Indian speedo after 1931 would have the Indian script. if you want to know it exactly you need to take it appart and see what is stamped on the bottom of the housing inside 7-28 would mean July 1928 for example....

Janos calls speedos with that type of bezel design "1924-28"

29/30 does no longer seem to have the "silver rings" around the holes for the trip meter and day trip meter.

Terry Marsh says here: http://www.antiquemotorcycle.org/bbo...ghlight=corbin that the 100mph speedometers started in 1928.

Hi,
Please help identify another Corbin speedometer. It is stamped 1930 inside.
The left knob/lever is speed hand locking device. By turning it you can fix the speed needle at current speed and it remains there until you release the needle by turning the lever back. On right side there is milage 0-ing knob.
Any ideas where it was used?

Nice find and that is the Police special speedometer, and unusual to see it in kilometers. The idea is that the officer drives behind the car to check his speed, then locks the needle, accelerates, pulls over the car, and shows him the speed he was doing. The problem with them is that the brass clutch in the middle, with little dogs on it, wears out relatively quickly and is hard to fix.

Thank you, Steve!

That Corbin tattle-tale feature always seemed like the perfect tool for a corrupt speed trap motor cop. Very easy for the cop to go 10 mph over the limit while chasing down the perp. However, I got a speeding ticket 2 months ago via modern radar and there is no arguing the accuracy of that tattle tale.
