Tillings Travel PL9356, 10DLY, Bristol MW / ECW coach. New to Tillings in May 1962, passed to EN as 356 in November 1963 and back to Tillings on 1st January 1971.
But in this 1973 photo, has Tillings fleetname but is on loan back to EN! Originally C34F, reseated to C41F in March 1973 which was presumably when it was repainted into NBC white. This is an unusual photo of a vehicle in NBC livery with a Tillings fleetname; in April 1973 Tillings vehicles were transferred to the new National Travel (South East).

Photo taken Saturday 14 July 1973, Rear of Southend London Road Garage
