Carton Stereomaster Microscope with Bausch Lomb Power Supply 1x-2x eye piece 10x This is a working microscope. I do not know much at all about microscopes, but I did plug it in and tested it and it zooms and all that good stuff (you still may have to calibrate this thing). The light source works great and is powered by the Bausch transformer (model number - 31-33-53). this was used in metalurgy lab, so it smells a bit like metal-ish stuff. I can not find any model for which Carton this is. The base is stamped with 9212. The eye-piece lenses are stamped with SW10X. The Stereo-master is 1X to 2X. Condition is OK. There is a crack in the housing for the right eye-piece (as seen). Please take a look at the pictures. Will ship international...
