I think it is less likely that this hilt is resin and perhaps more likely it is bone or maybe new ivory that has been artificially aged. It could still be old ivory, but i don't really see the point of all that added black stuff added to "age" the piece if it was really old. The black is definitely not natural aging IMO.
It shouldn't be too difficult to dissolve the glue that holds the mendak to the hilt. It would be what i would do if this were mine and then you could get a good look at the bottom of the hilt and maybe make a better determination.
