Pneumatic Rotary Tool with Offset Rotating Spindle oscillating sander 12804

Up

  For sale is a Pneumatic Rotary Tool.	Manufacturer and model unknown.
  The rotating spindle-head on this unit has an approximately 1"
  diameter X 3/4" deep hole which is offset from the spindle's
  center-line.	I have done a basic air test on this tool; it spins-up
  very nicely and sounds excellent.
