Old Bow and Arrows - Origin?

From the style of the bow, arrows and quiver can anyone tell me where in Africa they would likely have originated? Country or tribe would be much appreciated. Not sure if it's an old tourist replica or original. The bow is leather bound, with some patched fur bands. Draw string appears to be made from bamboo and held together with leathery material. Arrows are bamboo shafts with metal arrow heads (slight rust?) no fletchings present on any arrows and no signs of any ever being fitted.
