Looks like a nice old fighting blade .
The silver band/collar (it's a style) near the pommel is traditionally secured with a thick wire .
The stirrup straps would originally been inserted under the ferrule I'm thinking, then the rest would be hidden and secured under the wrapping .
If the gonjo has been replaced it is a good job .
The leather wrap on the hilt is a bit incongruous, not really suited to a wet jungle/salty ocean environment .
