Hello Frank,
I did one a few years ago and had the same issue to deal with but instead of striking the stamp off and compromise bbl thickness, I filled/tig welded the stamp over and engraved something more subtle where the stamp used to be and the word fox on the bottom of the frame, if you look at the first picture, you can faintly see the weld, once rust blued it blended in perfectly.... I thought it looked pretty nice
