Ivory Fist Dagger - Katipunan?

[David]

Can you show us any similar contemporary hilts for comparison Robert?
As for patina, i don't thing this images are clear and sharp enough to make too many guesses on age. Is this not in you hands yet José?
Ivory will discolor differently in different environments and with different amounts of handling. I would still like to see clearer, larger, closer, more detailed photos.
