Thorn Beta 4
This Thorn Beta 4 feartures the two part bowl - one piece is the bowl itself whilst the
other is the refractor ring. The inner reflector in some models also has hooks for a dome refractor, but this
lantern doesn't have those optional extras.
Fitted with a 2-pin porcelean bulb-holder, it would've originally been fitted with a
tungsten bulb.
Made from polycarbonate, it's now starting to go a little bit yellow with age.
It was originally installed somewhere near Bodmin, Cornwall and was rescued from the council's
skip by Dave.
