Supreme Prototype? Multimeter
When I first saw this meter and the hand lettering, my first thought was it's a homebrew that someone made from a Supreme dual meter movement and spare parts. When I opened it, I found that the bakelite panel it was made from was actually the back of an unused, undrilled, Supreme faceplate for a model 450 Supreme tube tester. Also, all the holes are precisely spaced and drilled, even the large round hole for the meter and all the parts are the same as parts used in other Supreme models at that time. This leads me to believe that this might be a pre-production prototype the engineers at Supreme were using to test one of their meter circuit designs. 7"x10"x4.5"
