Niya bowcase and quiver info?

[Folkert van Wijk]

I am looking for more written info and pictures or drawings from the Niya bow case and quivers.
I would like to know whether the quivers where sewn together and sewn to the bow case to?
Was it only made from leather or was there some wood also?
What about an attachment piont for the tying it to a belt or such? I do see some loose ends of wich one semes to have been braided.

The attached picture is what I have so far...
