Description

Ramsden’s Enterprise Continued, English, c. 1820, finely stamped in individual block letters “Worthington & Allan, Late Berge, London.” This 3-1/4″ (8 cm ) long (closed) monocular is constructed with an interesting variety of materials, the 1-3/8″ diameter achromatic doublet set in a silvered (now darkened with oxidation) brass cell bound in green leather, the conical main tube of silvered brass bound in green rayskin, the drawtube of silver over brass, and the eyelens mount of dark stained ivory. The Galilean optical system provides clear bright images of low magnification. Condition is good, the tube coverings a bit rough. This is the first example we have seen of the “Late Berge…² signature, and as such is an important document in its own right.
