In case of "composite" keris: the strangest photo ever I have seen, taken before 1920 probably in Aceh. Mendak-Selut are very close to ones on pompous Gowa keris (with hilts depicting Bhima(?) in lalitasana), hilts are looking like Banjarmasin. I remember to have seen a specimen very much like the left side sheath with a Madura hilt.
It seems, the left side keris have seen some practical use
.Pesi is the week point and is getting bent easily (according to english sailor tales about adventures in Singapore
