Hi Johan,
Welcome to the forum. It seems that I am late to the party.
Regarding your keris, the hilt and pendongkok is Malay Peninsular where the hilt is rather beefy. Sulawesi also have this beefy hilt form, but it is a bit different. This kind of hilt normally will be paired with a thicker sheath as well. This is common on the east coast of the peninsular particularly in Terengganu and Pahang. West coast sheath tend to be slightly thinner - more towards Sumatran style. I think the blade probably is also Peninsula - Pahang or Terengganu; however I don't have enough evidence to support that. Just a guess. We don't have much other than guesses at the time being.
A few days soak in sour coconut water IMHO would give the blade the so called "traditional" look. It is just a bit sad that the tip probably had been reshaped. But this also can be taken care of. Overall in my opinion it is a decent keris you have there. Have a nice day.
