Dale: The Zielman (or Zielmann, the pub has one n) was ridden by Doug Downen of C.S. Cortina.
Jamie Swan: you had it right on the Corky, "the Corky was built by Harold "Corky" Gulbransen in a backyard shed that is about 6 miles from where I live." Corky is also listed as the rider, riding for the German Bicycle Sport Club at the time.
