Killer piece that is mostly threadless from just above the lower WG lip to within about 3/4" of pinhole top.A huge bubble was trapped at the wiregroove and blew the threads out *completely* around the entire circumference of the insulator pinhole and expanding out to a little under exterior of the insulator. Piece is very impressive in person and will be a top shelf piece for the specialist. Satisfaction is guaranteed with this piece and everything else I offer.
