It has Hindu/Buddhist significance, though this does not necessarily mean that the owners of these weapons were Hindu or Buddhist. The peoples of Indonesia have always been inclusionary people and have adopted both Hindu and Islamic symbolism in a syncretic manner along with the original animistic traditions that existed before these influences entered the archipelago.
I think Michael was on to something in regards to origin early on noting the circular rattan wrap on the OP's gun that i have only seen on Dayak weapons.

Thank you for the explanation of the word "Bandja" David! That explains a lot!
I agree the "katon evok's" (woven ratan knots) point out of the Borneo direction.
But on most of the blunderbusses you don't find these kind of knots, even if they are from Borneo. And than it will be a lot more difficult to nail down the origine.
