This early 19th century large sized single draw telescope has a beautifully figured mahogany barrel and measures 35 inches fully extended, 20 1/4 inches when closed and has a 1 5/8 inch diameter objective lens. The eyetube retains its original dustslide and with engraved makers name: ""T. HARRIS & SON LONDON/ DAY OR NIGHT." A fine example from a very prominent early to mid nineteenth century instrument maker. Circa 1810.
CONDITION: This 200 plus year old telescope survives in good working order with expected wear from a used antique maritime instrument. The brass single draw tube has numerous tiny surface dents and the mahogany main tube is with some wear to the old, dark brown finish from years of shipboard use. The telescope does function and adjusts to a clear image.
HISTORY: “Thomas Harris & Son, Opticians to the Royal Family, No 52 (Opposite the British Museum), London." The London telescope maker Thomas Harris (about 1750–1827) brought his son, William, as a partner in 1806. By 1817, the firm was located on Great Russell Street, across from the entrance to the British Museum, and presented itself as "opticians to the Royal Family." In 1846, the workshop moved to High Holburn Street; it remained in business until the 20th century.
