Thanks David,
Yes, it was a bit nostalgic to read this old thread again with comments from some forumites that unfortuanetly aren't active anymore.
I fully agree with your comments about mislabeling and grains of salt etc but I have checked all the European museum collections that are available online, too. And I haven't found it in any of them, even if they seem to have almost all kinds of Indonesian swords in there collections. So based on this "negative fact" my conclusion is that, until otherwise proved, I prefer to label it Moro based on the two pictures above (2 > 1

) together with the collection notes that came with them about provenance.
But it would be great if someone else could contribute with an additional piece to this puzzle...
Michael
PS Thanks for the help with the pictures kronckew!
