VTG Tribal South America or Philippines Bow Arrow Spear Fishing Hunting LONG 65" For Sale

Vintage tribal hunting/fishing bow and arrow set.
Arrows/spears are bamboo, and the bow is made of a very light but strong and dense hardwood, something like heartwood or leatherwood.
Age and origin unknown. I have seen really similar examples from Guyana, Colombia, Brazil, and the Philippines, and something approximating these that are from Papua New Guinea (these are not PNG).
These all show normal wear and possible signs of use, see photos.
Ships free.
Thanks for looking!
