Gun-sighting telescope

This achromatic telescope was made for military use as a gun-sighting telescope. It is made of brass and focuses by rotating the eyepiece end. Cross hairs, visible when viewing through the telescope, allow for accurate sighting. There is an objective lens cap. The inscription on the focusing tube reads: 'G.S. TELESCOPE X 8 / No. 2187 / W.G. PYE & Co. / CAMBRIDGE / 1918 / NP 18'.
