Punal, Gunong with and unusual blade

[Battara]

Ones like this nice one with it's blade size, pistol grip style, and embellishments (bling - which I like ), indicate to me that this piece may come from the mid to late 1920s. Obviously this once belonged to a datu (or at least datu class). Based on the okir on the silver mounts, this might be perhaps Maranao in origin.
