Hi Maurice,
first, sorry about my late reply to your very interesting pedang. A shame that the handle is broken. Here some of my thoughts about it. I also think that it is from Lombok, me was told in Indonesia that this pedang with this type of handle coming from Lombok, have also a look to this thread, special #16:
http://www.vikingsword.com/vb/showth...ghlight=pedang. In the beginning of the 90ties last century you can find a lot of this pedangs in Bali antique shops and every time it was told they are from Lombok. Of course this isn't a guarantee that it is indeed like this.
I am with you that the inlays are done well, this could be a indication that they are old. I have had such a pedang with inlays as well (it's long time sold already), when i have bought it I was sure that the inlays are old, later I get doubts but frankly said the inlays weren't fine like by your example. But what I remember well, the blade was like yours very black stained. This is IMHO done to highlight the silver inlays. So I don't think that the black surface is old patina. This could be done in old times but as well recently. Like Alan I have seen blades with such inlays where I have been sure that this inlays are added for a better selling-price purpose but on the other hand I think to have seen blades with inlays which have been early collected but can't remember where.
Sorry that I am not able to give you new informations.
Best regards,
Detlef
