My 45 LB sniper also has the Savage rear sight, but no maltese cross. The cross does appear at the front of the lower forestock however. I have also seen the cross on the front telescope pad.

I remember discussion about this marking years ago on the Enfield forum. Someone asked why a maltese cross, and someone answered "cause it's for putting round holes in square heads".

Please forgive me if I have not used adequate political correctness in this post.
