What looks like a bevy of medieval torture tools is actually a early 19th century set of German neurosurgical tools.

It contain 17 compartments which accommodate a full set of instruments made from unplated polished steel, brass and horn. They are signed by Zitier, Heine and Sandill and it is likely that the boxed set was made specifically to accommodate these instruments. Around the central trepanning brace there are two fixed hand held trephines, two detachable handles and trephines attachments, a scalpel, Hey saw, elevator, brush, scissor handled spreaders, a starter trephine and two raspatories. Just under the handle of the trepanning brace is a small instrument with detachable screws which connect to the handle by means of an oblong shaped loop. The small screw would have been turned into a section of cranium and then left in place, allowing it to be easily removed with the handle.
