Hi Norman,
another 'javelin thrower' (

) .....but my throwing was in the '70's
I can't help thinking this is African, but the pictures are a little small to be conclusive. Also strange that there are no barbs..so possibly unlikely as a hunting / war spear

..but have to agree its a 'thrower'. A nice thing.
Perhaps, on reflection, it was dual purpose, the raised ring could provide 'grip' for one hand whilst the other is gripping the 'coiled copper' end, when used as a long range 'stabber' ...which could be easily pulled back after wounding a victim (hence no barbs

) but, balanced enough to be used as a missile if necessary.
Regards David
