CCUAL:
Thanks for bringing these pics back up. That is probably the best example of this rare knife that I have seen. Remarkably complete and looks as though it comes from the same time period as shown in the picture I just posted above.
The sticker on the scabbard says:
BOLO SWORD
TAGALOG PHILIPPINES
Obviously not a Tagalog knife.
Like Indianajones, I have been looking for one of these for a long time.
