Hello Detlef, Wonderful sword!! I fortunately did not see this when it was for sale, for unlike Jose I would have been bidding on it.
I have always wanted a Visayan example of these wavy bladed swords. My congratulations to you on finding one, especially with the original scabbard and twin Bakunawa-hilt.
You know who to contact if you ever get tired of looking after it.
Best,
Robert
