Request for comments and insights on a Keris Madura

[Paul de Souza]

I just acquired this keris Madura kagok, I think that is what the wrangkra is called. I think the blade is kemardikan. I am intrigued by the pamor. Is this a "new" thing or a legitimate old pamor. Can't seem to find a picture of it. Would be grateful for comments on the keris; blade and dress.
