A fine, rarely used Georgian camera lucida in original sharkskin case. Although unsigned, it is in the style of Dollond with an over sized ( 33 mm.) tightening knob to the inclination joint. Extending to 60 cm. with the usual gradations for distance, it consists of a simple, flawless prism with blackened ray shade (minor scuffs). Bright brass with original lacquer and housed in it’s flawless black, sharkskin case with both closure hooks intact. Red velvet liner and construction date it to 1810-1820. Case measures 25 x 6.5 x 2 cm. I have a signed example by Dollond exhibiting this same construction of the enlarged, milled knob for ease of use.
