Here is another silver fitted gunong I was lucky enough to acquire from epray. All hilt and scabbard fittings are of coin silver except the guard itself which is made by sandwiching a copper plate between two thin silver plates. The guard had been bent at some point which caused a crack to develop in one of the silver plates. On the plate on the very bottom of the scabbard is engraved "Fox Mindanao 1912". I did my best to get a clear photograph of the engraving but this was the best I could come up with.
As to why the plate looks brassy I do not know. Any comments about or information offered on this piece would be greatly appreciated.
