This is a "mostly" New/old stock 10ER Shopsmith Speed Changer in original box. The base casting was broken in shipping to a previous owner. I replaced that casting with an undamaged one from another speed changer which I bought for this purpose, hence, the "mostly new/old stock" description. All other parts are original as they came out of the box. The paint match on the replaced casting is very close as you can see. This unit was never used and is in pristine condition encluding the orginal belt set. I disassembled, cleaned, lubed and adjusted this unit so it is ready to run. In original box with mounting screw, nut, belts, instruction sheet and speed chart. Since the average speed changers sell for around 150.00 I think one in this condition is worth my asking price.
