Ken,
Very nice job. I suspect when we are all long gone and someone comes across your sword they will speculate on when the repair was done. You've matched the materials and pieces so well that I expect our future fellow collectors will think it must have been done back in the day when so many skilled sword makers and repairers were still around: "Man, look at that repair--almost impossible to see--must have been done by some old craftsman--nobody today could do that ..."
