Your Kris and my Barung are the first acid etched Moro blades blades that I've encountered.
The person that I got the Barung from told me his great grandfather which was a quartermaster in the Army, acquired it from the Philippines during the Span-Am War. He said that it was up on a wall in his house until a few years ago. So to answer your question about it being added after, your guess is as good as mine.
He had a Taming on EBay several months ago that I missed out on.
