I was fortunate enough to finally track down two complete examples of the Operay Multi Beam. The earlier model from the 1930’s came from an O.R room in Green Bay Wisconsin, and the explosion proof model came from a hospital in Southern Mississippi. Both these lights are complete with original wiring. It is quite unique and rare to get both of these hard to find historical surgical lamps. We have another 1930’s Operay listed along with our 1940’s explosion proof. Check out the additional photos on each piece.
