Hi Eric. Thanks for the additional photographs.
This is definitely a sundang of Indonesian though it is difficult for me personally to pinpoint origin. If it came with original dress it might be easier. I know Kai has suggested Madura, but i am having a hard time seeing that. If i were forced to make a guess i might suggest Sumatra. It is a lovely sundang though. It would be great to see it with some new clothe. I'm not sure that you have access to the anyone in Holland to do that kind of work though. I personally would hesitate sending it back to Indonesia to a mranggi, but maybe you could find someone willing to work from line drawings and tracings of the blade and do the finishing work at home.
