Thank you gentlemen for your input, and I am happy I learned new things about my Ganesho-Garuda-Himero-Naga would be keris.
However, I provided the link to that older thread just to provide a fairly recent example in response to Detlef's question as to whether I am expecting to see a Hindu Ganesha keris made in Muslim Java. And the answer is clearly and unambiguously YES. I have seen not one but a few clearly (in my maybe poor judgement) Javanese recently made kerises with Ganesha and Garuda (both Hindu).
So I reiterate my original question:
why is Roland's keris Balinese and not Javanese as I suspect?
And what makes this blade older than say 10 years or so?!
Regards,
Marius
PS: As opposed to Roland's oppinion that his keris has a smooth/shiny surface, all I can see from the photos is a rather rough surface typical for Javanese blades. Of course I might be wrong as photos may be deceiving but that's what I see.
