I agree that the pendokok is very interesting, but the hilt looks late 20th century and the carving looks non-traditional to me.
I couldn't tell you if the blade is at all old, but it doesn't seem to have much finesse. The ricikan looks pretty stiff and not quite right. Still, it is a bit unlike anything i have seen before in some ways. It looks something like a skilled foreigner's attempt at a keris. I don't think it would be fair to call this a proper Tajong.
