G'day Ferry,
Thanks for your reply. I appreciate it.
Someone showed me a picture of what the person said was a Nagaruncing; a couple of days ago. It was very similar to yours, it looked like a new a 11-Luk Nagasasra.
I am a bit confused because someone else assured me that Nagaruncing was tangguh Pajajaran.
As far as I know, the only Nagasasra-type keris tangguh Pajajaran was made by Empu Hanjani and then, it was only a NINE-Luk.
All may be revealed in the ripeness of time.

Thanks again.
Cheers.
