Willem, I mean
in other regions.
Somewhere I have read that the Banjar hilts were quite popular and that's why they were imported to other regions (I can't remember in which keris book I have read this at the moment. But I will get back to you when I find it unless some of the other collectors find it before me) .
Now and then you see the Banjar nunggak semi version for instance on Javanese keris. Both more recent combinations, like at "HH"

, but I have also seen them on keris in old collections and museums.
In Tropen there is a keris collected in Lampung with a similar Banjar hilt as yours (below). But the rest of the keris doesn't look like neither a traditional Banjar nor Lampung combination so it's hard to know it's story...
