hi jim, interesting thoughts on the one that was billed as a 'klewang' by it's previous owner who mentioned it might have been confiscated from pirates. could be chinese with the point reground. here we go using terms that just mean 'sword' locally. it was purported to have come from malaysia.
i also have this bornean (?) parang on the way from birmingham*,

while it looks a bit like a dyak parang ilang, it's apparently not a mandau (double knife). the blade supposedly is from around 1900, but the dress has been restored. will have better idea when it arrives (would have been easier to drive the hour up there, but it's coming via Royal Mail

).
* the UK one, the Alabama one woulda been a two hour trip from home in morgan county.
