There was a piece on him in "Octane" a year or so ago that had him pictured with three 917's, all in the green and white livery of Piper Racing. I attended a vintage race Hockenheim four or five years ago in which he participated and some people told me about him them. Very down to earth farmer apparently, who has a deep need for speed.
