From Luftwaffe Central: "Our symbol is properly called the "Sigil Trephanus." It is a line-drawn form of an exploded-view schematic of a 17th-century skull trephine, with its final form being credited to the pen of our own J1 Statik. The original device was wound and spring-driven, in order to bore a fine hole in the skull. Our symbol is based upon a Z-plane view of the moving parts inside, with each being shown at all possible points of movement. One of these appeared on eBay once. We did not have the resources to purchase it at the time, sadly. Our use of the Sigil first appeared in 1998."
