This situation stimulated greater thought: modifications were brought to the Mk.I. It was mentionned above that the "List of Changes"of the 9th June 1941 introduced the No.4, Mk.II while the Mk.I was declared obsolete. The 13th February 1941, an "Instruction to Proceed"( verbal instructions, a telephone call for instance, to start the production before written confirmation was sent to begin the production ) was given to the Singer Manufacturing Co., the maker of the Mk.I, to produce the second type of No.4. The new type was identical to the Mk.I : the dimensions were the same as well as the components. A variation was introduced : the blade, which was of circular section without the fluted ( cruciform ) blade. The tip had a screwdriver shaped end.
The manufacturing process of the Mk.II was identical to the Mk.I, except for the machining of the blade. By the deletion of the four milling operations, time and money were saved, the production increased and a serviceable weapon was still obtained. From 1941 to 1944, the Singer's total production of this type of bayonet was 1,141,782 made. Singer was the sole maker of the Mk.II in Great Britain and produced them until 1947. The costing price was 6/91/2 each, circa 1/40 of a weekly British worker average salary. A gain, in term of war effort. But the British government was still uncertain about the supply of rifles and bayonets from local production. It ordered more from Canada ( Small Arms Ltd, Long Branch, Ontario ) and the U.S.A.
