Hi Nathan,
Nice older 19th century kris!
But a challenge to restore it to former glory. The binding will be difficult to do, I am not able to do something like this. I have a kris in my own collection where a friend of mine had given it a new binding, maybe not the best one but adequate IMVHO.
The pommel seems to be indeed made from banati wood, this one I would clean with 000 steel wool, oiling it and giving it a polish with antique wax. The fittings are from silver? Good that they are all present. The scabbard I would also try to restore, I guess that it is soft wood?
Good luck with this project, it would be nice when you would show the restore steps here.
Attached are pics of my one with the steps of the restoration.
Regards,
Detlef
