This is a vintage microscope marked "Wollensak-Rochester, U.S.A." It is also marked "100 Power Pat. Appl'd". I have no knowledge in the field of science and its instruments so I can't make any firm comments on this item. The exterior does have tiny spots on the band which is marked. When looking into the microscope, t are a lot of tiny dots on the lens. I don't know if this is normal or if the lens has to be cleaned. It measures a little over 6" tall. It is auctioned in "as is" condition. Winner pays shipping. Insurance is optional. I accept Paypal to a confirmed address, money orders or personal checks.
