G'day Joe,
When I said Dutch klewang I was referring only to the blade. As you pointed out the rest looks to be South-East Asian. I am only assuming the blade is European because of the letters stamped on it. The G stamp is only part of a larger marking. The rest has been worn away and isn't legible any more. If it is a Dutch klewang blade, maybe there is someone on the forum who may be able to decipher what it used to say. I don't know anything about klewangs, but I am sure there is someone here who does. Osborn's G stamp is only found on officers' swords, not on munition grade blades. It is also stamped low on the ricasso, not in the position or orientation of the blade you have posted. I think it is very unlikely this blade has anything to do with Osborn.
Cheers,
Bryce
