I am selling a protoype tool I bought from an estate that the person was an engineer for Ingersol Rand. 
I since then changed professions, and I will never use this and other tools I purchased. 
If you have any questions please ask. After production the person was given one of each tool he helped design. 
Kinda of neat back story and explains why it's black with no IR labels. 

The Ingersoll-Rand 8" Air Geared Orbital Sander is crafted for sanding and smoothing paint, wood, body filler and fiberglass. The compressed air power, rotary power tool is used as an abrasive accessory for material removal. The power and strength of this orbital sander gives you a clean, swirl-free finish.
