My 1944 Lithgowicon has them. They look like punch marks with a 'disturbance' around them. Mine is a Sportco 25/303. Thanks for the information. I would like confirmation on the steels used in later Lee Enfields including the No4. I've been told that the American built No4's used a stronger alloy than the Britishicon and these alledgedly withstood 7.62 NATO proof loads better than the Brit made ones.
