Folks especially those with an interest in Lee Enfields or more to the point anyone with access to the List of Changes or the Rifle Subcommitee minutes of the Small Arms review commitee may be able to answer precisely why some rifles were stamped EY or E.Y. on the barrel and Knox form and ayt what point this was approved, the criteria for downgrading and when the practise ceased to be done. I would also like to know if it was similar to a BLR/BER tag being attached to my SLR? Answers on a postcard please. No seriously I am curious and also sure that the reasoning behind it will be documented somewhere! Dont bother with Skennertons LES etc as I have those and Edward Yule is out as rifles not wire wrapped are thus marked!
