Not much to bow to here i'm afraid.
If i knew what specific pamor adeg it was i would have stated it originally, but given that pamor wengkon forms a border around the very edge of the blade i don't think this would be called adeg wengkon. Hard to tell from the photos. There are many variations on pamor adeg and frankly i am not familar enough with them to know.
Again, on origin i am only making a somewhat educated guess, but i could be Jawa Solo. Anyone else wanna take a shot?
