These two plaques in Loftus Town Hall records that the town adopted Motor Torpedo Boat 57 during Warship Week from Novenber 29th to December 6th 1941.
Motor Torpedo Boat was the name given to fast torpedo boats by the Royal Navy, MTB 57 was a Vosper 70 ft, with Hall Scott engines, armaments were two 21-inch torpedo tubes, one 0.50-inch machine guns and two 0.303-inch machine guns.
Fortunately this excellent photograph of MTB57 in action exists which I was kindly allowed to re-use thanks to http://www.navyphotos.co.uk/
Also in the town hall is a letter of thanks from the Commanding Officer of the Coastal Force Base in Maddalena, Sardinia
