I have a 1974 SCV shirt that Gail Royer sent to me early in '75. I have the 1977 Blue Devils triple crown shirt, celebrating their 1976 "triple crown"
wins at World Open, CYO and DCI. I inherited a couple shirts from the 1969-70 years of the Troopers and Kilties.
1980 27th Lancers, and a couple dozen from the 1980s/early 1990s.
