If i were to do anything this would be my suggestion from the get-go. As both a collector from outside of the culture as well as someone with a conservator's viewpoint i usually prefer not to do any work that permanently changes the piece structurally and cannot be reversed if one wanted to return to piece to the originally collected appearance. A new, separate collar would serve this piece well and should not be too difficult for a skilled craftsman working outside of the culture to construct.
