Keris Madura with Thai influences

[Alam Shah]

Hi all,
The blade looks like a Carita form probably from Pattani. The hilt, I concur with those whom attribute its origin to Madura. The hilt cup, needs replacement whichever that you intend to use. The sheath is a Pattani styled "sari bulan" (crescent moon).

I do have a proper example of this Northern Malay Peninsular ensemble (see attached).
