This is the original Wilmot Breedon key.
The rear light blind, many brochures show a pull tassel that hangs. However, the 'Crusader' literature boasts "..the rear light blind can be lowered or raised by the driver as desired".  It is possible that A C Gotrel assembled it as shown with a pull cord (that leads to a position near the driver) to block out following headlights.  Original door handles have been re-chromed.  Interior door hardware and original woodscrews have been replated in nickel since this picture was taken.
