Double Ritter Reflektor dentist's wall light

For collectors or enthusiasts, very rare double dentist wall lamp from the 1930s by ritter, reflektor model, this one is german made but I believe it was also made in the united states for the american market. The single wall lamp model is already very rare but this model with both on the same mechanism is impossible to find, I have searched even in the archives I can not find an identical one. It is in very good condition, traces of time of course but no shock, twist or other, perfectly functional, the entire electrical system has been redone, water drop switch on the reflector of each lamp, in each reflector a blue glass filter and a fresnel lens all in perfect condition. The movements are all perfectly fluid, the rotation mechanisms of the ball joints are magnificent, a unique and very efficient system. It is a superb collector's item. Perfect in an industrial loft decor, with modernist scandinavian furniture from the 50s, 60s, and 70s, arlus lunel stilnovo wall lamp, chandelier, and floor lamp.
