[EDIT]
There is not really a lot that can be said from this photograph, now is there?
I agree that it is Buntel Mayat, i agree that the workmanship is on the lower end of the scale. I wouldn't even begin to go any further based on this image. Even when i shopped it up a bit to reveal a bit more detail i still wouldn't comment too much more.
What is it you really want to know about this keris Amuk? Direct questions usually lead to direct answers...
