Tom,
Flynn had the patent and it was sold through Flynn and Peters. Peters was a drycleaner in Ardmore, originally from MA like Flynn. I was keeping that a secret from the site until the book came out. Oh well, it doesn't matter as the story should be in next month's Fore, the Merion newsletter.
John Yerger III was instrumental in the discovery of the Flynn patent.
Winged Foot had the baskets for a short time. There's one upstairs in the archives that Neal Regan was kind enough to show me.
