May be I am completely wrong, but if there are this spelling (very comfortable) Bali/Lombok blade (in which this blade certainly doesn't fall), there must be also Lombok/Sumbawa and Lombok/Sumbawa/Bugis.
Lombok and Sumbawa has ties also after Mojopahit and Gelgel, which are Bugis and Selaparang.
I think there could be a possibility, a keris with such characteristics would appear in Lombok (even more in Sumbawa).
(I would also like to ask somebody with greater experience (so everybody) about Madura influence on Bugis blades and blades from Sumatra, Lombok and Sumbawa )
