Some help here, please

Hi guys,
While looking in antiques shops for weapons more of my type, i have just stumbled upon this keris.
The owner (seller), knowing nothing about these things, searched the Net and 'managed' to find an example he 'considers' similar to this one, dated 16th century.
Needless to say he is asking a fortune to sell it, based on such 'conclusion'.
Is there any way, by looking at these lousy pictures, to estimate a date on this keris?
Whatever the conclusion, i will never buy it, due to the conviction the seller has that this is an almost 'medieval' weapon.
... But i would in any case appreciate your guys opinion, just for the sake of knowledge.
These pictures i am posting were authorized by its owner and my query here does not constitute any unexpected procedure.
