Mr Bernard Williams, the last owner of Kerr's Drapers, 6 High Street, Dartford operating the Lamson Rapid Wire propulsion.

According to Proctor, the system was installed in 1900 and rented from Lamsons for seventy years before Kerrs purchased it for half a crown (£0.125).

A receipt that travelled by the cash carrier - a momento of my visit on 24 September 1977

The cashier's point reconstructed in Dartford Museum.

Close-up of the car and propulsion. Presumably the green paint is so that this cup could be distinguished from others. The photographs above show green and red cups. I have not seen them painted elsewhere.
