In great condition with fine optics, Circa 1770-90’s.
Telescopes such as this example, were widely used during the 18th century in Europe and here in America during the Revolutionary War. A well made piece, most likely English made, incorporating finely turned brass furniture on an round tube of solid Birch wood. The optics are excellent; sliding lens covers on both ends of the telescope, and a single draw using multiple sections of brass tubing fused together.
There is no name on the draw near the eye piece, but probably dates from the 1760s-90s. The tube is just under 15.5 inches long, and measures 24 3/4 inches fully extended.
Brass surfaces are in fine condition. The wood is fine as well with a few small dings and scratches.
A very nice usable accessory from the 18th Century.
