This is a wonderful vintage microscope, complete in a very protective wooden box! The microscope measures approximately 5" by 6" at the base and approx. 8" high. Powered by AC, it has two lights; one underneath and one on top. The switch has four positions: off, top light on, bottom light on, and both lights on. Works great. There are two lens for the bottom, the unused one is stored on the base. Includes a package of micromount cards, instructions for slides, and a box with a total of 11 slides which contains various leafs. Some of the labels are worn off of the slides. There is one corner on the wooden box where the wood is somewhat chipped and worn. Manufactured by the General Science Service Co, Minneapolis, Minnesota. Thanks for looking and good luck!
