British Gunsights evolved during the Dreadnought Era from simple quadrant sights to cam-worked species with telescopic, periscopic or open sight vanes which applied drift and ballistic corrections.

Telescopes

Telescopes were often used to provide crosshairs and a magnified view of the target.

In 1907, the following types were supplied:[1]

Pattern Number Manufacturer Power Field (degs) Diameter (in) Remarks
1306 Ottway 3 9.5 2
1663 3 9.5 2
1663A 3 D.N. 9.5 2 Ottway illumination
1663B 3 D.N. 9.5 2.52
1697 6 9.5 2
2110A 7-21 D.N. 4.5 - 1.5 2.52
5-15 D.N. 6.25 - 2.33 2.52
3 to 9 D.N. 9 - 3 2.52
2110 Ross 7 - 21 4.58 - 1.52 2.52 Ross illumination
2134 5 - 12 D.N. 5.83 - 2.92 2.52
2018 high 1.153 bore sighting
2019 low

The meaning of the "D.N." designation is unclear. "V.P." is used to mean "variable power".
