Soft foam Endo skull. Bought on eBay. Sold as a T2-3D Dud Cast skull.
Detailing is missing in some parts, but otherwise looking great.
T1 and T2 production style head. Likely T2, as there are Stan Winston Studios pictures showing a mold and the pieces molded, as well as a casting used to sculpt skin on top that matches this foam skull - various details matching. Making no claims as to whether it is a direct casting from SWS molds or it is a copy of one of those castings.
Included some of the eBay auction pictures as well as some pictures after I painted it with metallic rubnbuff and ivory paint for the teeth.
