- vol. 29, 7 May 1880, p. 360
The sum of 500 pounds was awarded to Mr. Robert Wilson of Messrs. Nasmyth, Wilson & Co. Of Patricroft by the Secretary of State for War in consideration of having applied his patent double screw propellers to the Whitehead fish torpedo. The high speed of 27 knots attained by these torpedoes was in no doubt due to the use of double screw propellers.
