Hello Gustav,
nice kris with great provenance!
I have watched this auction as well and when I decided to give a offer it was sold!
Be careful by cleaning the silver ferrules at the handle, most probable they are only silver plated. About the cord bands: I would let them like this and handle them careful, I have had the same problem, look here:

BTW, great pictures!
