1938–9 [Anstye, Hassocks] 
The names of the joint winners for 1938–9 do not appear on the cup. Evidently the outbreak of the Second World War disrupted the usual arrangements for engraving it. From 1939 to 1967 the league did not operate. From 1955 the cup was used as a trophy for the SCCA annual jamboree.
