Doug Spreng's AMA bio says 1960 champ with Stormer and 1961 with Flat-Top Stormer. Maybe the interviewing person has mistaken Ed saying he attended the 1961 nats with an Orion variant.
UStik - That is correct. Just for the record :
1960 Spreng, Youngblood, Mathis
1961 Spreng, Brown, Brett
1962 Kazmirski, Nelson, Ritchie
1963 Kirkland, Ritchie, Usher
1964 Weirick, Ritchie, Brooke
1965 Weirick, deBolt, Coleson
