Robinson's Disc on a Torpedo Director Pattern 2390[1]
Robinson's Disc was a disc that could be added to a British Torpedo Director to permit the enemy's inclination to the line of sight to be read off directly.[2]
It appears to be, or to have been developed from an unnamed 4 inch diameter disc described in the Annual Report of the Torpedo School, 1914, apparently conceived and first used aboard Blonde.[3]
