Strange twist core Moro _____???

[VVV]

I picked up this sword at a local auction this Summer.
It's quite small, has twist core and I assume it's 19th C?
It also has a false edge.
What do you think it is?
Could it be a remodeled old twist core kris??
Do you have any reference pictures of similar swords???

PS I have had BIG problems etching it and have tried both FeCl and household vinegar.
Somehow I don't manage to get enough contrast. Any hints?
