I believe that anyone who suggested to you that this was from Palembang should be immediately taken off your "expert" list.
I do understand Kai's suspicion about the blade being shortened. It's length does seem proportionately abrupt. But closer examination of the tip makes this less clear to me. You might be able to tell more if the blade was cleaned and stained and a pamor was revealed.
