The Antique Partnership has dated this piece to the 19th Century.
This telescope I guess is about 1830 although experts may be more definitive due to the construction. EXTREMELY POWERFUL for its size. It focusses well with a sharp image. Some spotting to one of the fixed central lenses but otherwise excellent. The leather covered brass barrel is in good condition with stitching intact. Focusing lens cover slide working.

Sold together with a later made mahogany presentation or desk stand. Signed on the last tube Watkins & Hill Charing Cross London. Some scratches scuffs and small dents as to be expected from Naval or Military use (Shown in Photos)
