Sears Craftsman/Double A Products 8" bronze bearing belt driven grinder.
In the mid to late-1950s, this was the lower price point alternative to the similar 66130 ball bearing 8" grinder with rotating wheel guards.
By around 1959 both grinders were merged into the 66110 ball bearing machine with fixed wheel guards.
First offered around 1955/6 in Sears Medium Gray, this one is slightly newer with the Power-Bronze finish.

This grinder was used by a previous owner for lapidary work.
It was rigged with a water or oil drip reservoir and wheel wiping brushes.
I made a purchase offer to the eBay seller for only the grinder, June 2016.
No further history is known.

Update 8/31/2016:
Disassembled. Washed guards, pulley, tool rests, and fasteners in Zep Purple with hot water.
Wiped the body clean with mineral spirits.
Masked bearings, oil caps, decal, and pulley bore with blue tape.
Walnut shell blasted body, guards, tool rests, and pulley.
Filled non-original holes in the body and guards, using pipe plugs and bolt pieces.
The bolt pieces were secured with Perma-Lok® and ground flush.
Polished tag drive screw and tool rest bolt heads with emery compound on a spiral sewn buffing wheel.
Washed tags in Dawn liquid soap using a tooth brush.
Touched up logo tag with blue and red Sharpie pens. Then sprayed both tags with Krylon Crystal clear coat.
Primer: Rustoleum 2x gray (body, pulley, guards, tool rests).
Paint: Rustoleum Champagne Mist Metallic primer/paint spray, two coats.
Reassembled using SAE30 non-detergent oil.
Most of the guard attachment bolts were missing or non-original, replaced all with ¼-20x¾" socket head screws.
Replaced worn shaft external retaining rings (24mm size).
I decided to leave the non-original tool rest threaded holes for possible accessory attachments.
I also left the non-original motor switch and power cord holes in the body.
If I power this grinder with a rear mounted motor, the switch in the photo below will be used.
