I have recently agreed to purchase a 98 Mauser done up in what I would call "Germanic" style, DSTs, half hex half round barrel, full rib, flattened bolt handle but I digress. Will take some pics. after I have it in hand. The ? is calibre, on the LR it's marked as follows - 2,5gGBP and a large S - is this an 8x60 vs an 8x57? or does the S have another meaning? Any comments appreciated. --- John303
