Quite a few Southend Transport drivers have helped Ensign Bus out with the collection and delivery of dealer stock vehicles. Here we see former Moore Brothers and Eastern National 20PVX, a 1959 Guy Arab with Massey body. Latterly EN 2015, it was withdrawn in 1974.
Owned by Ensign from 1975, it was exported to California in 1976, see here for a photo. It is seen here in the blue livery used for Lesney staff buses.
