Unknown pamor and dapur - Djogja keris

[KLUNGKLUNG]

Dear all,

Hope some of you will enlight me about the pamor and dapur of this 3 luk keris. It has been cleaned recently.
Both sategal spikes worn so if not a Pudak sategal then a Jangkung Mangkurat is feasable?
The rendering of pamor Kupu Tarung shows a close resemblance with mine. There is a alternating motif all the way to the tip ( still there but slanted).
Thanks for watching and comments....
