Entered for Race B was the Maserati 250F with which Stirling Moss had won the 1956 Monaco Grand Prix. The car was driven by Peter Heuberger but did not start the race. A battle between Duncan Dayton and Joaquín Folch-Rusiñol ended prematurely for Folch-Rusiñol, leaving second place to be decided by a fierce battle between Barrie Baxter and Tony Smith.
