While searching, I did find an interesting thread.

Both blades presented here have roughly the same style of Greneng as mine. The Gangya of original blade (Maguindanao with Sulu style hilt) of that thread has a similar strong bend like mine, while the CCUAL's blade (Sulu) has a similar "elephants trunk" area.
The hilt-blade angle of the first blade (Maguindanao) seems to be quite small and similar to mine.
