I had problems with Don Palmer's driver IDs in this photo.
RSC results show a #94
Bill
Schmidt finishing 14th in #94. There was no record of a #3 or #34
in the event or of a driver with the unlikely name of "Fritz Fritz".
But in
Art Evans' book "Golden Gate Remembered" pg.74 I found an entry listing for #34 MG TD entered by W.H. Giles and indeed driven "Fritz H. Fritz".
