This microscope is unsigned by the maker on the brass-work. It is however marked in ink on the bottom of the leather-covered base, but the signature is indistinct. Some early French drum microscopes of this design are known that, while not exactly identical to the instrument shown here, are signed by Camille S├ębastien Nachet (1799-1881). One such example is located this collection. Similar microscopes are also known that are either unsigned or are signed by other opticians. One closely resembling this microscope is located in the Harvard Collection (inventory Number: 1081a) and is dated 1845-1850; while it is also unsigned, it is attributed to Nachet. Another microscope very similar to the one shown on this page, but slightly larger is also in this collection.

The microscope is supplied with a full compliment of accessories which include two eyepieces, three triple button objectives two of which have their own nosepiece, a brass trough with glass bottom for wet preparations, a camera ludica, a stage condenser on an articulated arm, two glass slips with brass clips (an early form of live box), an ivory and ebony stage disk for mounting opaque objects, and a set of dissection tools.

Stamped in ink on the inside lid of the case is a name and address, Werner U. Pieper, Heidelberg, Schafergasse 69, possibly that of a prevous owner.
