This uncommon style of Central Desert throwstick or hunting boomerang is called the Swan Neck , Beak or Number 7 . These unusual boomerangs were used for fighting, ceremonial purposes and sometimes for hunting Emus. The Aboriginal hunter would dress up in a grass suit and hold the boomerang up to simulate the neck, head and beak of an Emu. This camouflage allowed an Aborigine to get closer to the Emu so that the large bird could be speared. Most of the Swan Neck throwsticks that are sold are larger than this one and are covered with red ochre because they were used for ceremonial purposes. This one lacks the red ochre. It was probably used for hunting and/or warfare. Almost the entire upper surface has longitudinal fluting. The lower surface is stone scrapped smooth. This throwstick was probably made in the early to mid 20th Century. It is in very fine condition, but the beak was broken off and then carefully repaired. It is difficult to see the repair from the fluted side which is the side that would be best displayed. I do not recommend throwing this one.
