I am not convinced that the belalai gajah is an add-on, but there does seem to be something strange going on there. Possibly a good traditional washing might reveal more.
Certainly not Javanese as Shahrial has said. Malay, possibly Sulawesi???
I am curious why you suspect about 1860 as a possible date. It is certainly possible, but it is a bit more exacting than i think most would venture. Do you have some sort of provenance that has lead you to this date?
BTW, i like the dress, especially the brass pendokok.. Is the toe of the sheath made of horn?
