Hello Bill,
Yes, staining, staining, staining!
I still have my reservations to call these assimilated pieces from non-Moro sources kris...
How long is the blade? It would be nice to verify wether the blade was forged in the Visayas or wether a captured/traded Moro blade got recycled - maybe the laminations could help short of examining the tang and base of blade?
Regards,
Kai
