Description

A good Victorian camera lucida in brass-unsigned but of the highest standards and with unusual construction features.

The C-clamp and extension arms are of normal construction although the smallest extension is not demarcated.  The prism head is where the innovation is seen. A  flip-type sun filter of rectangular form in a brass frame with 4 screws, a pivoting prism  head by knurled nut and an articulating arm to the prism (flawless)  by a ball and socket joint (much as you would see on a bullseye condenser pivot). A light stop of tear drop shape is on the other side of the prism. Closed it measures 8 inches (20 cm.), open and extending to 16 inches (40 cm.). The flame mahogany case measures 10 x 3 x 1 inches ( 25 x 8 x 2 cm.) with eared hooks (one tip broken) and heavy hinges to the rear. Georgian examples are either in a maroon card case or sharkskin (George III and IV).
