Antique 1920s Bausch & Lomb Optical Co Brass Microscope w/ Wood Case & Lens

The product is an antique 1920s Bausch & Lomb Optical Co brass microscope, housed in a wood case with lenses included. I am not a dealer or expert in microscopes. This was my great grand fathers from medical school. He went to Palmer College of Chiropractic in the early 1920s. I'm trying to let the photos show the specifics of this microscope. This collectible scientific instrument reflects the craftsmanship and precision of early 20th-century optical technology, making it a unique piece for any science or microscope enthusiast. With its vintage charm and historical significance, this microscope is a valuable addition to any collection of scientific instruments or antique laboratory equipment.
