Big & little bow + 2 types of arrows - where are these from?

Hi
I found these last week at a thrift store. There are 2 size bows (1 large & 1 really small), 2 kinds of arrows both with different sizes in each group + 1 group has wooden tips with barbs on one side & the other group has metal(?) tips with 1 or no barbs.
Also these have a couple really long Shafts, but the arrow head us small.
Where are these from?
I believe the smaller bow and wood arrows are S. Pacific?
Finally, are these real or souvenirs?
Thanks very much for any help!

 

Based on the tropical feathers and the woven quiver, they may be from the Brazilian Amazon.

 

Too well done, too detailed an' lethal for tourist crap, I believe. Got no idea from where...but something tells me they're for fish, versus land-critters. Nice catch!

 

I thought it had to be something small - especially with the size of the metal ones

 

arrows like that were often used for birds and monkeys....

 

I did image search on quiver & found S Pacific island that looks like the quiver and metal tips arrows, but i also found arrows that look like the wooden ones t hat were Indian?!

 

This is my bows' ends - doent wood look the same?

 

Komokwa, the quiver matches S Pacific island, as do some arrows & maybe small bow - but doesn't wood on my large bow, as well as wood arrows , look like wood from 'Old Indian Bow' listing?

 

I have found some similar looking bows. Looks like black palm tree bow?

 

New Guinea?
