Identify Switch Panel

Thanks for the additional information. I have to confess i had never heard of a Turner car.

Efandem moved to new works in Wolverhampton from Birmingham in 1911. One of their specialities at least until WWI was dynamo lighting outfits for motor cars, motor cycles, cycles and boats, although they seem to have applied later for a patent: 29.049: "Electric switch for lighting sets of motor, &c., .c\cles," J. Eaton and Efandem Co. October 14th 1920.

As to installers, from a 1959 Motor Magazine article by Robert Thwaites about restoration of a 1914 TURNER, car No.1250: “Electric lighting was at this time an optional extra... and is by The Efandem Co., Ltd., of Wolverhampton. The dashboard unit is a particularly beautiful piece of work, glass-fronted, with voltmeter as well as ammeter, and a very neat rotary-type switch.

Turner’s, who were also in Wolverhampton, fitted a dynamo lighting and starter set for £35 extra in 1913.
