Gonjo iras, pamor.

Well now you've done it Alan. You've provided an "unsupported opinion" and then gone on to support it with a reason! Is that allowed?
But seriously, i only ask because i have a Javanese keris that is gonjo with pamor, so i must ask, is it because of this specific pamor? Surely not all gonjo iras blades with pamor are from Palembang.
