Odometer Rotation

[Bob Moseley (RIP)]

Hi gals & guys

HELP

The more I restore the less I seem to know. I was quite happy with the knowledge that Ford odometers rotate downwards and GM odometers rotate upwards. The Ford knowledge was based on the Waltham speedos. Then whilst restoring a Stewart Warner speedo, allegedly out of a Ford, shock/horror the odometer rotates upward.

At this stage I haven't rebuilt the speedo to determine the correct rotation of the speedo drive, and maybe, hopefully, the gearing is reversed to compensate for the rotation. All I know is that now I have to get manufactured another odometer for the S/W speedos.

Confused - Bob
