Make unknown - this has been knocking round our spares drawer for a long number of years.

Used condition -  Lots of lovely character bashes and light tarnish marks. At a guess I would place this as dating to 1950's/ early 60s. Glass intact. Switch appears to operate correctly but has not been tested. Terminals appear free from corrosion.

Fixing bolt and nut present and operating correctly , but bicycle mounting bracket is not present

Complete with original bulb , but this has not been tested.
