[A. G. Maisey]

Nothing much to add to what has already been wriiten, just a few comments:-

1) I doubt that Pamekesan ever had a kraton, its status is as a Kabupaten, a regency, I'm not all that familiar with the history of Pamekasan, but I believe that it never had a Sultan, nor a Sunan, it was always under the ultimate control of Sumenep, which was a Sultanate. It might have had an Istana, ie, palace, where the Bupati (regent) lived, but if no Sultan or Sunan, it could not have had a Kraton.

2) dress is Central Jawa, Solo style

3) not tilam upih, but as YS has said, brojol

4) the "upe" spelling is perfectly understandable, a non-native speaker hearing the word could easily give it that spelling, as could a poorly educated native speaker --- I get emails frequently from several people in Solo who left school before they entered high school, and writing in both Javanese & BI their spellings sometimes do take a bit of effort to understand.

5) I'm of a like mind with Rasdan on blade origin, I would give this blade as Madura without a second though --- if I did have a second thought I might give it as East Jawa, thus including Madura, but throwing the net wider. Pamor ngulit semangko --- kulit semangka --- and a couple of other alternate spellings.

Edit

I think you might be right about Tuban Jaga, that gonjo looks very much like it could be nguceng mati.
