Still with the tapak kuda hilt -- I would imagine that, given the same geographical and cultural milieu (S and E Sumatra), the tapak kuda would have been a logical accessory than another design on the other side of the mountains, as it were.
Pak Rasdan can solve this mystery -- can you show a shot of the top of the hilt? Or maybe you can tell us if it's a tapak kuda.
Whose golden keris is that anyway? Sultan of Selangor? Or, as my imagination runs wild, is that the elusive golden keris salvaged from the Flora del Mel?
