Thanks for the replies.
Rick: Yes, indeed it is something to be grateful about
Mr. Maisey: "In the mean time, you may care to have a look at the old "good keris" thread in the archives of this Forum". That's exactly what I've been doing. I guess thoroughly understanding the ricikan and dhapur characteristics from the books will make it easier to absorb new info when I get the opportunity to physically encounter kerises.
All these desire to learn about tangguh is mostly because I really hate to get "pretenders". I am happy enough to know that the keris is authentic and so for now, all I'd like get out of the "tangguh game" is to be confident to a certain degree about the approximate *ERA* the kris was from.
Well, some tangguh skill will also enable me to better enjoy exhibitions like "Kris for the World" that I just attended ... It was baffling for me to see some large kelengan krisses that look like they were just made couple decades ago being labeled as "Singosari" by the judges.
I'm looking forward to your info about "non standard ways", if you can find it.
