Taking a long hard look, I think this keris is a keris debek from N Malaysia/S Thailand.
The sampir is rather compact, but is definitely more akin to the other keris debek sampir I've seen. The other possibility is Banjarmasin, but that form does not have overhanging daun like this. As for a Minang origin, the roundedness of the underside is something I've not really seen in Minang kerises. Another point is that if this is Minang, the batang should be tapering, but this specimen here does not.
Blade-wise, first impression was that this was a coteng-type blade. Meaning it comes from the Singora area in S. Thailand. Such blades can look very very Bugis, but the styling of the base of the keris is the part that differentiates it from Bugis blades from the South.
You could consider a buntut like the type on the example below (not my keris).
