Dan, my rifle used to belong to RobD. Same rifle, been meaning to uncover the markings for years. Been busy doing some research and found several former snipers of the period (mid to late eighties) and I think I've found the guy the rifle was issued to. If correct he won best sniper at the UKLF sniper concentration, Otterburn in 87 with this rifle. Furthermore it would look like it's one of the very few L42's inherited from the Royal Anglians that never broke down and went the full distance with 3 RGJ
