Nice gunong Philkid. It looks to me to have genuine age, late 19th-early 20thC. The metal work is nice. The only reason i can think for the bubbling on the sheath metal is that perhaps the gold color is not the main metal itself, but some kind of finish or plate. The copperish metal on the hilt could swaasa, but it could also just be copper. The other metal looks like brass to me since it appears slightly tarnished which gold would not do. Nice ivory.
Falcon, welcome to the forum. I'm sure a moderator would tell you, but since i'm here

this is not a buyer/seller forum, it is purely for study and discussion. We do have a swap forum for such things. I look foward to hearing your opinions and viewpoints on various blades and subjects.
