Hello Ian, The fact that some of the hilt material seems of a later date had also occurred to me. Also the quality and workmanship of the blade appear to be of a much higher quality than that of the hilt itself. On quite a few of these that I have seen the fittings were made of silver. Maybe this was a later replacement? As leather scabbards most likely have very short lives in the Philippines I would say that this could also very easily be a later replacement as well.
