Hello Jose, I agree with the most what Kai has written already and don't think that the handle was such a hulu jongo like you have given it now. All the lopah petawaran I've seen until now with a blade without decorated bolster has had a rather simple handle so I think that the top was covered with a silver capping instead of an elongation.
If the handle was upside down I am usure about but it is good possible.
But a good restore job without doubt, congrats!
Regards,
Detlef
