Heavy Duty Bench Grinder

Found this at an estate sale for $15. Replaced bearings and cord and it runs smooth as can be. The one remaining tool support is in sad shape so this machine will most likely be dedicated to rough grinding on one side and felt or wire wheel on the other.
There is a through hole in the front of the base parallel to the shaft. I assume this was intended for some form of auxiliary tool support. I'd be interested if anyone has information of how that was used.
Most interesting thing about this grinder is the uncommon centrifugal switch configuration as shown in the pics.
Two copper rings representing the 2 sides of the centrifugal switch
Brush/Counterweight which completes the circuit.
