Specs
2018-03-08: mcmaster has two units on the way. One sourced locally at auction, one being shipped eBay freight. The eBay unit is pretty complete, although cosmetically isn't as nice. The local unit is reasonably complete, but may be missing a few simple bits like the wedge.
2018-03-15: both units have arrive. FabExchange unit unfortunately in much worse condition than I thought based on the pictures. For example, the inside electronics have been stripped out, and really the unit is just mostly taped together and missing a lot of screws. Its also missing drive belts and misc other covers. Fortunately the eBay unit, although has some missing paint and a little rust, is otherwise in pretty good condition. Preliminary tests indicate that it likely works
2018-03-25: contacted K&S, was told: “K&S no longer offers any manual wire bonder products and has ceased all related support services. You may want to contact Sharon Siso (…@mpptools.com) from MPP.”

Initial checkout
Controllers
Belt broke shortly after I started using it due to it being old and what not
Measured:
McMaster doesn't sell OD below 4“, so need to make one myself. I've ordered 1/8” material and will try to fit and join it. Suggestion is to fit it on the machine to length, then cut to allow for 10% stretching (ie cut 10% off).
