Description

This telescope has a round parallel brass barrel covered with brown leather, possibly lizard. This covering is a replacement.  The push-on cap for the objective is missing.  The objective lens is an achromatic doublet and the exterior lens is cracked.  It has nine brass draws (an unusually large number), a four lens eyepiece (missing the lens nearest the objective), and a flared eyecup with a sliding cover.  It is signed "Adams   London" on the smallest draw, with the eyecup to the left.
