Little keris for comment and a few question

[Sajen]

A while back I got this little keris (patrem?) in a mixed lot.
It's a pretty well made piece in my humble opinion and all seems made together and fits pretty well.
My questions:
-- Would you describe it as patrem?
-- Has anyone seen before such a joint between gandar and wrongko?
-- Would you restore the broken piece from the gandar?

Thanks in advance!
