African bows and archery

[thinreadline]

Here are some bows and some arrows from my 'heap' . Dont know their geographical origin but would welcome comments .

BOW 1 shaped hardwood stave length 160 cm , max width 5 cm , bamboo 'string'.
BOW 2 shaped hardwood stave length 190 cm , max width 4 cm , bamboo 'string' incised decoration at one end.
BOW 3 'natural' branch hardwood stave with only minimal working , 145 cm long, 3cm wide max, plaited leather 'string' , grip covered with leopard skin.

The 5 arrows all have bamboo shafts and vary between 105 - 170 cm in length ... all have separately fashioned 'heads' apparently of hardwood.
The arrows are not necessarily associated with the bows . The bows appear to be quite old whereas the arrows to my untrained eye look much more recent . I have owned all of them for over 20 years and they came from a house clearance in a North Wales village.
