An early 3-draw brass telescope by Bancks – circa 1820

An exceptional 19th century brass terrestrial refracting telescope, signed on the eyepiece draw, “Bancks & Son, 441 Strand, London.”  Robert Bancks II worked at this address between 1805 and 1830.  The telescope is further inscribed in script, “Instrument Makers to His Majesty.”   This would be the Prince of Wales.  The telescope measures 15” long when open, and closes to 5 3/8”.  The lens is a 1 1/8” achromatic.  The telescope is finished in brass with a mahogany front.  Condition is excellent, noting a one inch age crack in the wood. The original glass produces fine images of good contrast.  The front lens element is fitted with a brass cap, while the eyepiece has a sliding dust cap.  This instrument is not only a very attractive decorator piece, but is a practical, usable telescope from a very reputable manufacturer.
