The Pay N Pak button is most likely from the late 1960s, just prior to the George Henley era (driver) which lasted from 1970 to 1975. Henley (a very talented and successful driver) was in the marine business as his full-time job, and also a sales rep for Hamilton jet drives. The Budweiser button probably is from that same early to mid 1970s period when Billy Schumacher and Mickey Remund we're doing the driving chores for Bernie Little. The Atlas Van Lines button would would be mid to late 1960s when Bill Muncey was at the wheel. When he wasn't hydro racing, Muncey was giving motivational talks to groups (Kiwanis, Rotary, etc.) on behalf of Atlas Van Lines and writing a monthly column for Powerboat Magazine.
