Sorry, mate. I have a few, but jealously guarded.
(..including WR LT-capped Explorer and Super-Magnum Explorer!)
There is a guy here in Australia who deals regularly, I'll keep an eye out for suitable stock amd PM if something comes up.
Meanwhile, see if you can locate Pete de Coux, collector-cartridge dealer and auctioneer on your side of the pond. He may be able to help.
