Check the listing for details. Antique Bausch & Lomb Early Pre 1930 Microscope Brass. Listed at 260.00 USD. Vintage Bausch & Lomb Early Pre 1930 Microscope Brass. Purchased at an antique auction is is a brass Bausch & Lomb microscope. The microscope has 2 lenses that unscrew easily and the eye piece unscrewed easily also. The eye pieces top glass is cracked but you can still see through the microscope, the bottom mirror is in very good condition with no cracks. The plate on the microscope where you put your specimen is cracked and it looks like some sort of bakelight covering. The mechanism to turn it up-and-down moves easily.Tilts back easily. Measures approximately 13" tall with the base measuring 5.5" depth x 4" length. Seems to work well except for the cracked eye piece lens. I am not an expert on microscopes so please refer to the photos as they are part of the description. 32
