Banjarmasin keris?

[Jean]

As promised I attach the pictures of my recently acquired Banjarmasin kris with the following comments for discussion:
The blade has a rough surface and it does not seem to be Javanese nor Buginese; a specific feature is the presence of small dots of pamor (tambal) regularly spaced along the blade. This is also found on another kris from Banjarmasin shown to me by another collector, does it mean that this style of blade is indigenous to Banjarmasin?
The hilt in Sumatra style is made from gilt brass and in excellent condition, the selut and virtually all the intens are still present.
The gayaman sheath is typical of Banjar, the gandar in 2 pieces is fully covered with very fine cotton thread which was replaced on the top part and a bit damaged at the tip but I will leave it in this condition.
