AN UNUSUAL 1½IN. TWO/THREE-DRAW SHAGREEN AND BRASS TELESCOPE BY DOLLOND, LONDON, CIRCA 1790-1800
handsomely signed as per title on the objective dust slide, the objective set in a single front draw, two standard draws terminating with flared eyepiece -- 15¾in. (40cm.) closed
An interesting instrument and possibly a one-off, being needlessly complicated by having the objective set in an additional front draw (which was used later by many manufacturers as a shade slide, whilst keeping the lens fixed to the main tube). Whilst the instrument has good magnification and focus, the eyepiece may lack a lens which would provide a wider field of vision.
Sold for £496
