The following was extracted from the 1907 Leitz catalog:
Small Travelling Microscope. This microscope is ready for use after spreading the foot, drawing out the tube, and setting the mirror and stage in position. It is provided with micrometer adjustment like Stand V, coarse adjustment by rack and pinion and condenser with iris diaphragm. The box accommodates three objectives, two eyepieces and a brass box for a bottle of cedar oil. It is fitted with a lock and handle, and measures 25X15X7 cm. The whole apparatus weighs 4 1/2 pounds.
In addition to the Abbe condenser, this particular example is also supplied with an aperture stop holder and three stops.
Another earlier version of the Small Travelling Microscope is also represented in this collection. It differs somewhat from the later example shown on this page with respect to the tube, stage, and its storage. The stage on the microscope shown here is permanently attached to the stand. It is turned to the side when the microscope is placed for storage in the case. There is a lever that locks the position of the stage when setup for use. In contrast, the stage of the earlier example of the travelling microscope is not permanently attached to the body of the microscope. For storage in the case, it must be removed from a slot on the body of the microscope and placed in a slot located in the case. While the later model has a draw-tube, this is absent in the earlier model. Instead, in the earlier model, the tube which carries the ocular is stored in the outer main tube; it must be removed and reversed and then screwed to the outer tube to assemble the microscope for use.
