Thanks for your input Alan. I know exactly what you mean by the Madurese indicators and was going to mention that, but unlike you i was unable to say what the same time it did not seem quite right for Madura. You explanation was very helpful for me to understand why i chose to keep my mouth shut. LOL!

Thanks also, Ian, for the close-ups. It's alway difficult to date any keris blade solely from photographs (and even in hand), so the more detailed images we can provide is always helpful in any assessment.
