Probably not fair to say that the rest is not "authentic". It looks to me (and of course with not real provenance who is to say for sure) that this is a PI blade that fell into the hands of a 3rd cavalry soldier who then made it his own with the additions. Maybe it was a battle score. Maybe it was a gift or trade. Maybe he just bought it as a remembrance of the time, but i still read that as a very "authentic" piece of history.
