Ron, i would actually like to see a shot of the keris shot from the over top with the hilt and pesi wrapping material removed completely and the focus placed on the sirah-cecak (front bottom surface). I might be crazy, but to me it looks like the core of this blade actually extends all the way to the bottom and that additional material was then welded
around the iras gonjo giving the appearance that an entire gonjo was welded on after the fact. Not sure if i am making sense with my description, but what i see in the part of the sirah-cecak that is visible looks very odd. If you are uncertain of the area i am asking you to photograph please see the gonjo diagram on Alan's website.
