A GOOD 18TH-CENTURY 2IN. NAVAL SINGLE-DRAW TELESCOPE BEARING DUAL SIGNATURES FOR DOLLOND AND RAMSDEN
the tapering mahogany tube with brass draw signed Dollond London and Ramsden London, bulbous eye-piece with dust slide -- 38¼in. (97cm.) closed; contained in later canvas rod case

Jesse Ramsden married John Dollond's youngest daughter in 1765, thus aligning two of the greatest instrument-making families in London. Dollond was justly famed for the quality of their optics and zealously guarded the acquired rights and subsequent patent to the invention of the achromatic lens against London competitors - a share of which was given to Ramsden as part of the dowry when he married Dollond's daughter. It seems that in the instance of this lot, Ramsden simply acted as a retailer and had a somewhat hasty-looking signature added.
