Trephanation kit on eBay

This magnificent trephination set, circa 1750, is up for auction on eBay right now. Trephination is an ancient surgical procedure where a hole is drilled in the skull. (Here's an article I wrote back in 1998 for Boing Boing Digital about modern day people who undergo elective trepanation for kicks.) This stately set of tools is housed in a velvet-lined oak case. The current bid is $5,500 but the reserve has not been met. From the auction description:
