The 1955 Blue Ribbon Trial, organised by the Victorian Sporting Car Club, was probably held on June 26th.
This was apparently the fourth Blue Ribbon, and was directed by Vic Cox. It ran in daylight from dawn to dusk on the “shortest day of the year”. Of the 26 starters, 16 reached the finish with Bob Scarlett’s Vanguard winning. As was the custom at the time, navigators, so crucial to the performance, were not mentioned!
