Bradford 687, CAK687, a Karrier E4 with Weymann H30/26R body new in 1938, rebuilt by Samlesbury Engineering in 1950. It was withdrawn from service in 1962.
It was one of two trolleybuses given a special livery to commemorate Bradford's Golden Jubilee of trolleybus operation in June 1961, in this case restored to its original 1938 navy blue and cream livery.
