Hello Thomas,
can you explain me why you think that this is an 21th century piece?? It's a golok from Sunda (West Java) and a very nice complete piece. A little bit search here by the keyword "golok" will help you to find similar examples. Have seen this piece and bid byself on this "Singapore sword"!
The inlays will be indeed from brass, maybe a short version of the city from where it coming. No gold!
Regards,
Detlef
