I guess the drive gear would be a different setup for each brand of vehicle, eg the gear diameter and the no. of teeth.

There is a Smith's Pump currently on E-bay:

The body appears similar (but mirror reversed) to the Morris CS8 pump, but the drive gear is quite different. In fact, the E-Bay pump looks very similar to the arrangement on Ford CMPs. I wonder if this was actually design for a Ford application, or some other British vehicle such as the Austin K5?

The Smiths Pump body looks quite smaller than the CMP (Ford or Chev) pump, so I would expect a smaller output of air. Are there any specs regarding the volume/pressure output of these pumps?
