Which is a more accuraate rifle? The No1 MK 3 or the No 4 MK1

[5thBatt]

Ian Skennerton has personally viewed this rifle & felt it was legit, obviously strongly enough to write a small bit on it in the TLE
The receiver is a MkIII* WITHOUT a cutoff slot, this is not the normal production for a 1939 Lithgow, it would have a cutoff slot if it was taken from normal production or from another rifle.
