Yes I like kris with 13 luks and I intend to collect them, I am a bit confused too, on both of these dapurs. Perhaps, we should raise the questions: why are there many versions of Parung Sari, what is Parung Sari or its origin or may be its functions as compared to the legendary Sengkelat. Perhaps, its beneficial to see photos of Sengkelat and various versions of Parung Sari posted to this forum..Looking forward to see.
