For various customers, I have removed a lot of roll marked "made in Italy" and cartridge inscriptions/designations by peening the displaced metal back into the groove, filing, smoothing with emery. Very time consuming, but much better than just removing metal. The key is the judicious use of a light hammer like a gravers hammer and a selection of punches ground to a slight convex and mirror polished. You gently "push'' the displaced metal from the roll marking back into the divot from whence it came. Draw filing must be done with sharp files, well and frequently chalked. For final emery work, it is hard to beat the quality of the fingernail emery boards found at beauty supply stores...very good quality. Blending blueing or browning is the hard part to approximate the original finish. Several pre war gunsmith how to books describe this method in detail.
