Hello Carlos,
I think a decent piece for a nice price. I cannot see at the pictures if the keris exactly fits in the wranka, nevertheless it looks old and autentic.
On the webside:
http://old.blades.free.fr/ You ca find a lot of information about this piece i think.
Once i bought something too from this seller, in my opinion a reliable seller with knowledge from the kerises he sells.
greetings Martin
