Crazy cool old electrical device consisting of an old Jefferson Electric Mfg. Co. slide switch transformer powering a Bausch & Lomb lighting device with aperture. Lamp has adjustable height and angle.Not sure what this for, the long ago owner had an interest in Microscopy and photography. You could have used it to put a very focused little beam of light on something. Measures about 15in height x 6in width x 7in depth.
Condition: Use at your own risk! This is all outdated electric and likely not very safe.
Fine & fun material culture that inspires
