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".
