 Close-ups of the blade would be good. From this pic I'd guess this blade to hail from Madura, too.
Just one more comment: While collected in Thailand, there doesn't seem to have ever been any kind of keris culture among the ethnic Thai. Granted, quite a few keris are on display in the Bangkok palaces and occasionally one might have been worn at court but apparently more as a curio item (most were likely diplomatic gifts or war booties).
Thus, I'd avoid to refer to a keris as being "Thai" (as in "style Thai" or "Thai influences"). If anything, these keris are (northern) Malay, ethnically. Keris from southern Thailand seems like a reasonable/neutral description; however, Pattani/etc. would be much more informative IMVHO. We all know that modern state boundaries usually are a result of accumulated historic "accidents" - OTOH we're discussing cultural artefacts here and, thus, focusing on the originating culture does help. Sorry for the rant... 
 
Regards,
Kai
