Gentlemen! Let's keep this discussion civil and on topic please.
As someone who professes to have much less knowledge that either of you blokes i believe this discussion would be better served by presenting examples to support your positions rather than merely stating what you find suitable or unsuitable for classifying this keris. Though to be fair to Alan, he was fairly clear that his opinion was "not to be read as a tangguh type classification" and ended his comment in post #12 that "best
guess would be South Sumatera".
However, one should still address questions directed at even personal opinion and guesses in a snark-free manner.
