Hi Battara
I don't think its silver but aluminium or zinc, it feels light.
I don't have anything to test silver.
Silver on kaskara handles is mostly wire or thin plates.
Solid cast silver handle would be nice allthough.

I agree, lighter probably means aluminum, which might indicate a later (early 1900s) dating for the hilt. And yes most I see with silver are wrapped and decorated, not cast.
