Bausch & Lomb May Ophthalmoscope Arc-Vue Otoscope Set Medical w/ Case Vintage
older set perhaps 30's era or earlier. The set is as shown I am not certain it is complete and I have not tested it. The box has many nicks and signs of age and storage and inside it is in poor conditon overall. neat set that looks to be restorable and a good item for your collection.
