A RARE, POSSIBLY UNIQUE, 18TH-CENTURY SINGLE DRAW MAHOGANY AND BRASS SIX-FOOT CAMPAIGN TELESCOPE BY HENRY PYEFINCH, LONDON
constructed in four 18½in. sections with substantial brass threads, tapered eyepiece with dust slide, signed on removable double main lens assembly Pyefinch London No.194 with adjustable focal length indicator slide numbered '7 / 6', closed length assembled -- 75in. (190.5cm.)

Henry Pyefinch (fl. 1739-90) advertised a full range of instruments from Cornhill, London, but is generally associated with his optical instruments. He was prosecuted by Peter Dollond in 1765 for infringing the Dollond-owned achromatic lens patent, which Dollond won. This interesting telescope displays an image the correct way up which suggests terrestrial rather than astronomical use and was, presumably, once contained in a travelling box. Whether it was intended for surveying, military or recreational purposes is not clear.

Condition Report
Good overall condition for age, with little evidence of tube splits etc. The optics appear to work clearly and focus; the eyepiece dust slide is a period but later replacement. Threaded lens cap missing.
