Hello Henk,
Thanks for your reply,the dealer helped me out with the Wrangka, since I could only conclude that it must have been a Gayaman Solo, he told me that it would possibly a Grayaman Solo Nunggak Semi.
I agree that it is a nice object, and that's why I bought it

But how is it a better start than most collectors?
I'm very keened on having information about Kerisses.
When I start something, like this collection, I always start reading information before I put money in it, the more you can tell, the happier it makes me
Cheers!
