When fully extended, the glass measures about 5" high. When compressed, it measures about 2" high. The diameter of the base is about 2-1/4".The scope is brass, and the base tube is covered with turned ivory , which has split with age. See 2 photos of flaws to the ivory.

The eye piece is clearly marked: DOLLOND LONDON . They were makers of fine optical instruments from the late 18th century. The optics are in good condition, and can be focused. Clarity is quite remarkable! Don't miss this rare antique spyglass.
