Mid 19th Century Mahogany Cased Brass Bar-Limb Monocular Microscope c1850
This cased microscope is in overall very good condition commensurate with age and use. Optics are in good working order. Detachable sections and lenses all unscrew/screw smoothly. The microscope retains its original lacquer which has some losses and surface tarnish marks as seen in images. Case is solid and sound throughout - minor splits due to age of the mahogany and very minor marks from use. Internally in very good condition. Please see images as these form an important part of the description.
