That is a good question, anyone can answer this one specific and tell us where to find/read it?
I know that you can add Celebes to your enumeration according van Zonneveld.
Many source cite Sulawesi/Celebes as the actual origin of the Sundang in general. Even if this is incorrect i think it is fair to say that that it can be added to the Peninsula as at least one place of origin for non-Moro Sundangs.
