hi dear,
I think you have a good kris. I think name of pamor is Hujan Emas or Udan Mas like your name
Estimate the dapor is Tilam Upih with Tikel Ales. Good work from end of 19th CA or early 20th CA period, often called Nom. I like the pamor, looks like made by carefully and good pamor handiwork. So fine and clear. Specially at gonjo. It have a pamor Hujan Emas too. I think too difficult to make a pamor at bottom of gonjo.
The warangka is Ladrang Surakarta. Look so appropriate with the blade.
Congratulation.
