The mahogany case doubles as the microscope stand and a carrying case.

Underneath this sliding door is the removable front (eyepiece) lens.
This shows the microscope stored within the storage case. Note the accessory drawer.
The microscope slides into the dovetail notch on the top of the case (see top box, right). Extending to the left is a telescoping arm that supports the focusing target.
The eyepiece lens slides into the notched sides of the case (*). To protect the large front lens, a shade could also be slid into the case. It is missing in this specimen.
