Where is this sheat from?

[Sajen]

I found recently this blade and I think it's a Peninsula blade. Unfortunately is the kembang kacang broken but apart from this it's a very nice one in my eyes and it fit nearly perfect inside the sheath without any woodwork.
What do you think, will it be a good blade to complete my Coteng sheath?

Thank you very much in advance,
