British motor gun boat, 1939-45 / Angus Konstam.

Motor Gun Boats were the Royal Navy?s Spitfires of the seas. Bristling with small-calibre guns and machine guns, they served in a variety of roles during the war. In the early war period they battled against German E-boats in the English Channel, then went on the offensive, searching the enemy shore for likely targets. At other times, they ran support for Motor Torpedo Boats and were used to deliver commandos on various raids.
