The keris shown on P. 234 of Tammens, Vol. 2  does not share the same characteristics as the keris posted by gwirya. 
 
The Tammens example appears to be a ligan, or keris pedang; I say "appears to be", because all we can see is the outline of the blade. 
 
One thing is certain:- it is most definitely not a keris of cundrik form.
