Howard, you are brilliant! Got the speedometer out last night and cleaned it up as you suggested. There is evidence that the thing had been serviced at least once though certainly not be a pro as there were only three screws holding it to the cluster and the regulator and condenser were only hanging on by one screw and it was half way out. Suspect that could be part of my low gauge readings as grounding for the regulator and condenser had to be hit and miss at best.

Disassembled the speedometer as you suggested and the lubricant that was either very dirty or mixed with graphite or both had turned into a solid. Using a needle, I picked the solid lube out as much as I could then turning the speedometer upside down and using the back or the unit as a trough, I filled it with Vacuum Pump oil and let it soak over night. I'll include some pictures in a later episode. By the time I went to bed, everything us moving very well indeed.
