Wonderful blade almost identical markings as on one of Jim's shown. I can't add much to what Jim has said.
The kaskara treatment Jim mentioned is here:

Your blade is of the quality that would no doubt had a silver covered grip and pommel so a strip wrap would not be period/culturally correct, but would be better than the existing one which is neither.
Also, I think I mentioned grip/hilt attachment & coverings with some illustrative pics in the attached paper archived in the forum's Geographical Index.
