Hi PUFF. Since this thread you linked to is completely in Thai (which, unfortunately, most of us can't read) i was wondering if you have a question here. I could be wrong, but i believe the first keris posted is what is referred to as keris coteng which i think is probably of southern Thai origin. This one looks to be in pretty poor shape, unfortunately. The other keris looks to be a Jawa keris of Surakarta origin, at least based on the dress which is all that is shown.
On page 2 they get into a bunch of Bugis style keris which may be from a number of different locales including the Malay peninsula. Then they post a number of the Thai form again. Most of these examples are in pretty poor shape as well.
The first keris on page 3 is a modern Madurese tourist piece followed by another modern piece in Jawa dress of better quality. They then seem to launch into a discussion of hilt evolution showing examples of both peninsula and Sumatran forms. This part looks most interesting. Perhaps you wish to translate a portion.
