This fine long glass is the classic style of telescope popular in the early days of the Republic.

A ten-sided wood barrel telescope with brass furniture, it appears to have its original lenses which are protected by sliding shades over their apertures.

The instrument has a single draw marked Troughton, London. The Troughtons were well-regarded marine and scientific instrument makers in the 18th century.

The scope is 25 inches (65 cm) long when closed and 31 inches (80 cm) long when extended.

The wood barrel shows no cracks or repairs. The scope is “as found” and required no restoration. Considering the age of this telescope, I would rate the optics as good, with a small field of view.
