Code BA21060301: English Military Sighting Compass by T. Cooke & Sons, 1894
| This is a nice and large example of a military sighting compass made by T. Cooke in 1894. It has a brass case in excellent condition without dings or dents. On one side, it has a sighting vane in excellent condition, with a small mirror that may be slid along the vane. The mirror may be opened and closed. On the other side, it has a magnifying prism that may be unfolded to read the angle when sighting. It is in excellent condition and gives a crisp image of the chapter ring of the compass. Two lenses (red and green) may be used in conjunction with the prism in special lighting conditions. The compass has a flat needle with a brass jewelled cap. An aluminum chapter ring is perfectly balanced on top of the needle, so it may rotate along with the needle. The chapter ring is numbered every 10 degrees and marked every half-degree. The compass is very precise and finds North without any problem. Given such degree of precision, a button located under the sighting vane may be pushed to help the compass stabilize at North. A transit lock is activated when the sighting vane is folded to freeze the needle and attached chapter ring. It is automatically released when the sighting vane is unfolded. The compass is covered with a flat glass crystal in flawless condition without any scratches or chips. The glass is protected with a brass cover engraved with makers name: T. COOKE & Sons, YORK, ENGLAND, with serial number 1000 and dated 1894. It also has a military arrow (/|\) and the letter I, which means that the compass was issued when UK troops were in India. A threaded hole is located at the bottom of the case allowing the compass to be mounted on a tripod. This is a quite large and heavy compass, measuring about 12cm in diameter and weighing about 600g (1.3 pounds). Nice and quality ultra-precise compass. |
