The older Tioga beartrap headsets come as Paul said, stamped top nut, brass bearing cages and brass lock washer. Unfortunately though, they have been repopped to look identical. The original beartrap II headset is the same as above but has a rubber seal on the underside of the top nut to assist in stopping coming loose. The repopped ones don't have that or the brass bearing cages. There was a guy in the US replicating the headsets by adding the brass lock ring, but it's thicker than the original one, and a different colour.
The original boxes are grey, not black. Only the newer repopped ones come in the black boxes. The grey boxes have been re-done too, but if they look too new, then you know it's exactly that, new.
