Hi,
Judging from the blade form and hilt, I would associate it with Lampung, South Sumatra. As I hear from more senior collectors here in Singapore, the hilt has "Mickey Mouse ears"; It is quite a distinctive form. Most Minang Kabau kerises, which I would consider more Central Sumatra, are of the bahari form and seldom ganja iras. Non-bahari Minang kerises tend to look more Bugis than Javanese. South Sumatra kerises tend to have a more Javanese look to it. Like any generalisations, there would be exceptions to these assertions.
