Hi Michael,
Sorry for not updating you on this piece, earlier. When I showed pics of this blade to friends whom attended the
keris seminar and workshop @ Universiti Malaya (UM), there's no clear indication.. what was confirmed was that it's a malela blade, the dressing is typical Terengganu-styled.
From the blade material, it is not too old, no earlier than 20thC works, probably later.. Unfortunately, many were unwilling to give an opinion based on pictures alone.. as other aspects are not being abled to be determined.
