On a side note I heard somewhere that the aussies that packed SMLEs in Korea loved the no1 mk3 because they could use the sight wings as a quick and dirty 'battle sight' ie all you had to do to ensure torso hits at 50m was to quickly put the rifle up and put your target between the wings and over the front post and pull the trigger. Much faster than trying to line up the rear ramp and front sight or even a no4's peep sight. That coupled with the 10 round mag and the fastest, smoothest bolt action in the world must have made for an incredible volume of accurate fire.
