Compound Microscope in Case with Accessories, by Smith and Beck, London, c. 1856

Also called the "milk box microscope," The trunnions supporting the limb are fixed to a wooden board with places to hold eyepieces and objectives. The stand folds down for packing and the board slides into a rectangular box. The body pushes into a sleeve which allows coarse focusing and a mirror is mounted on a sliding sleeve at the lower end of the limb. One eyepiece is present. Inside the case is a loose eyepiece and a short body tube.
