I have worked with Stan, a totally world class player who certainly did know about mouthpieces. Indeed I know he was not accustomed to cutting off the tip, so as the Ebay listing says possibly a failed experiment "For that reason it must be stated that I cannot be responsible for it’s fitness to play and so should be seen as a historical purchase at the bidders own risk."
Or maybe just teaching a wayward Link a lesson it won't forget.
Whatever it was Stan was not in the business of refacing, he may have don some wacky experimenting for himself, but was not taking money off people for doing dodgy refaces.
Out of interest on a completely side note, I believe in those days in England there was only one main reface as such and that was Bill Wrathall, an extremely talented craftsman who also made and "refaced" movie camera lenses for Ealing Studios. You needed to know a thing or two about curves for that.
As a reference for Stan's tenor and flute playing:
