Gun-sighting telescope
This achromatic telescope is a heavy-duty instrument for military use. There is a focusing ring towards the eyepiece end and a pointer within the tube for accurate sighting. The body is made of brass and has a sliding shade of laquered brass to prevent glare from the sun.
The inscription on the barrel reads: ‘W. OTTWAY & CO LTD / EALING / 1914 / NO 249 / SIGHTING TEL: NO 4 MARK III’. Ottway and Co. had contracts with the Admiralty and the War Office.
