Robinson Disc[Inference] added to 2390 to set course of enemy as expressed as inclination.[1]
Note the lack of any graduations on the sighting arm.
Note the lack of any graduations on the sighting arm.
The Torpedo Director Pattern 2390 was a British Torpedo Director available by 1912 at least, and supplied to torpedo craft with heater torpedoes.
It was similar to the Pattern 1895, but graduated for higher torpedo and enemy speeds.[2][3][4] It would be mounted directly on the tube, and was a suitable substitute for an 1895 or 1193.[5]
It was not circular, and probably a 60 degree arc like the 1895.[6][Inference] It lacked graduations on its sighting arm, but by 1916 at least, they sported inclination discs.
The Pattern 2390a had more rigid pivots, sturdier construction, and a sighting arm that was solid rather than slotted, and made of hard rolled brass.[7]
