Looks like a car type Jaeger speedo to me. Can't imagine what motorbike that went that slow would have the luxury of a speedo?

This looks like a Smiths PA, or at least one of that family.  It's probably from an Austin 7.  These centrifugal speedometers were made in two styles, a rear drive which has a cranked bottle-shaped back to it making it 5" or so deep, and a parallel drive, where the drive enters the side of the casing parallel with the glass 1" below the glass.  The parallel drive ones went into petrol tanks where the drive cable ran through a tube in the tank down to a take-off on the gearbox.

If you locate a source for a an 80MPH dial face and a means to re-calibrate them, please let me know!

Ariel??  No, although I may have a tank for one.

I am afflicted with New Imps.

Hi,
Does anybody have any spares manuals or explosion views or any litterature of the Smiths PA speedo with
" a parallel drive, where the drive enters the side of the casing parallel with the glass 1" below the glass.  The parallel drive ones went into petrol tanks where the drive cable ran through a tube in the tank down to a take-off on the gearbox." This type was used on 1929 AJS, too! Starting 1930 AJ used the 45 deg bottleshape back.

I would be interested in a 80 mph dial face too

Tx,
Jari

Some Ariels use that system, so you will find some competition when one comes up on ebay!
