Can Someone Help Identify - Jambiya?

[HAM8T]

Hello Everyone,

I am still going through some decades-old stuff in our attic and garage loft and I have now come across this jambiya(?) which I am hoping someone might be able to assist me in identifying. A while back I posted one that was one made for the tourist trade. I am not sure whether this is one of the same type or the "real" thing.

The hollow(?) of the handle where the blade is set is filled with some strange-looking whitish substance. I poked it with a pin and it is hard like cement or maybe bone but looks like an insect's nest to me!

I would appreciate any help you can offer.

Thanks,
Helen
