An authentic Bausch & Lomb amateur microscope from the 1930s, complete with its original wooden storage case. Manufactured in Rochester, New York, this scientific instrument features a heavy cast-metal base, a polished steel body tube, and a rotating aperture disk below the stage. Although it is currently missing its eyepiece, the mechanical focusing mechanism remains smooth and functional, making it an excellent display piece or restoration project. This piece embodies the early 20th-century boom in accessible science education, allowing students and hobbyists to explore the microscopic world. It retains its historical maker marks on the base and stands as a handsome testament to classic American optical engineering.
