Sloper's drapery shop at 14-15 The Brittox, Devizes (now Boots). They also had a furniture shop at nos 11-12 (now Woolworths). The Gipe system was installed in 1929.

Tom Sloper invented a secure internal telephone system which was used in the shop and is on display in the Museum. It was used by the War Office in World War I.

Propulsions at the cash office at Sloper's. There were four lines and some assistants brought bills straight to the desk. (Photograph courtesy of Rog Frost)

One line of the system with two propulsions is on display in the museum. There was no car when I visited in April 2006. The system is a Gipe closed wire system no.10. (I'm not sure that the chain is authentic.)

The propulsion partly open, separating the wires which would send off the carriage.
