The story
The European Ferries Group was incorporated in 1935 as Monument Securities Limited, becoming a public limited company in 1949.
In 1957, Monument Securities bought a 51% stake in Townsend Car Ferries and in 1959 acquired the remaining shares. The same year Monument Securities changed its name to George Nott Industries Limited.
