There is a kris with molar hilt, which is almost a twin to this one:

also a very huge exemplar, much to big for the keris (judging from aesthetics of today), which itself is not small. It came to Historical Museum of Bern in 1914 as part of the Moser-Charlottenfels collection.
This means, this hilt (and kris) almost surely was collected before 1876, definitely before 1893.
