i recently bought the attached signal. It appears to be complete.
It is a remote switch; the lights show red if the track is dead, or green if it is live- the centre is illuminated at all times. I can't locate a wiring diagram, or instructions. It is a 1404, but the metal one was replaced with a plastic one in the 1960s. Any assistance most welcome.
Also il looking for a source of cloth covered wire to rewire it.
