Campbell GEV694 was an Albion PH114 with unknown (possibly Duple) 20 seat body new in May 1938, which was out of use by the time Campbells sold out to Eastern National.
It was disposed to AMCC of London E15 along with the rest of the acquired vehicles in October 1956. The photo was presumably taken at Pitsea.
