MILLER TOOL MFG
~ DIAL INDICATOR ~ mechanics shop tool ~ Model C
This company made a range of mechanics tools. Some speciality.
They seemed to make not many indicator separate models, but would sell the same models with different kits for different uses.
Not sure what the attachments here with this one are for, I have included pictures from the 2 catalogs I could find 1938 and 1956.
Very good working order.
Feels like it has a very strong spring - super responsive. I assume it was made more heavy duty as these are designed to be used by mechanics.
