Title

Wilson Screw Barrel Microscope

Description

The screw barrel microscope is made from brass and has an ivory handle which can be dissembled to fit into the original case. The microscope consists of a cylinder with an external screw thread. The microscope has a mounted objective lens with a condenser lens screwed into the other side to illuminate the specimen during observation. Coarse focusing is achieved by screwing the body tube along the screw thread which adjusts the distance between lenses. The microscope is also equipped with an extension attachment that is needed to mount the objectives when using the stage forceps. The instrument can be used as a simple or compound microscope, depending on how many objectives are used. The case has a red velvet interior that has compartments for the dissembled microscope and its accessories. The case is secured by two brass swing hooks; however, one is missing.

The microscope comes with the following accessories: 5 objectives (marked with dots from 2 to 5 and 4 retaining their caps), 1 stage forceps, forceps, 4 ivory sliders in a case, a partial wet slide and an ivory talc box containing mica discs for observation of opaque objects.
