Check the listing for details. Rare SPENCER REFRACTOMETER collectible American Optical microscope No. 740 Case. Condition: For parts or not working. Listed at 97.99 USD. Made in Buffalo NY USA. I believe this was made around the 1940's. I couldnt get the container to lock. The container still has the dispersion table in the back of it. The upper parts look to be in good shape.
