A few years ago, a NJ collector named John sent me photos of a 1938-47 Horni Signal fixed-face 4-way light that he had just restored.  The signal was originally hung at the entrance of an industrial complex in Sayreville.  John replaced one set of visors (that had been crudely snipped) with a new set. He repaired at least one door latch, and fully replaced the sockets and wires and hooked up a circuit board controller. He took the restoration further by drilling into the base and affixing the signal on top of a pedestal and putting a newly-machined finial on top.  The purist in me would have kept the light on the original hanger and hung it from the ceiling, but I also know I would not have had the patience to do such a thorough restoration in the first place.  Beautiful!
