| During the Second World War Villiers 
		again had to turn to making munitions.  They claimed that "some of 
		their production schemes considerably lowered costs compared with the 
		methods then used in ordnance factories".  The Government urgently needed 
		small four-stroke engines, most of which had come from America until 
		U-boats started to cut off supplies. 
		 Villiers offered to make an 
		entirely new unit to take the place of the American engines, and in four 
		months the first was ready for tests. They passed the tests and the 
		production engines were used by all three Services all over the world.  | 
		 A Mark 25C cylinder is being fitted to the 
		crankcase in the final assembly shop at Villiers' works, in 1953.
