Well Mick, you are probably right on this one.

I guess i got lured in by what appears to me to be better than average ricikan work than i've seen on other Madurese "Bali" blades. I did notice that the finish was wrong (though the photos made that a little difficult) but thought it might have experienced some non-Balinese washings to account for that.
That being said, it is my understanding that there is nothing like this coming out of present day Bali, so if you are correct then madura would be the place. All that aside Montino, this is still a very attractive keris, regardless of it's origins. Hopefully the price you paid for it is in line with it's true age and origin.
