Yes, I agree that we are looking at a non-traditional form, however, based upon what I can see in these images I am of the opinion that this keris possibly dates from around the 1930's or at latest, early 1960's. 
 
It is not very recent, as in being a part of the revival of keris culture that occurred after the late 1970's.
