Small Sumatra keris

[Sajen]

After I have received it I have had some taskwork surprises. The second white ring at the gandar have been from some sort of tape and the other one show by the hot needle test that it is from plastic. Then I have removed the silver cap from the buntut, see the pictures. The black ring and the original buntut are from real horn. The complete sheat have had a cover with clear varnish, I have removed it with steel-wool, the wood is very nice. I plan to replace the white rings with white water buffalo horn.
But I don't have a clear hunch how the buntut original have looked, here I want to ask you for help. Is it possible that the buntut also have had a white ring?

Thank you very much in advance,
