Moro / Borneo hybrid ?

[Royston]

Another oddity from my collection.

This one has puzzled me for a long time and I hope that someone will come up with an explanation as to what it is.
I have never seen this seemingly Barong / Parang Nabor combination before.

The hilt looks real and has some age. The blade looks as though it has been there for a long time, see the photo showing the blade / hilt point of attachement.
I am not convinced that the blade is as old as the hilt.
The scabbard is definitely a lot more recent.

I am looking for an opinion as the whether it is a known weapon, a hybrid or something that someone " Threw" together on a wet Sunday afternoon.
( Do I hear the word Souvenir ? )

As usual, all comments welcome.

Royston
