As much as i would like this club to be from south america (that would make it more real probably), i just can't see it anymore.
Santa Cruz islands have some dance wands with similar patterns and the black inlay see
http://www.faganarms.com/collections...rm-club-94-257 for instance (ignore form but look at the inlay!)
i've ordered a book about he material culture of the Santa Cruz islands (in german o joy!) that i hope will shed some light on the form.
But i'm suspecting a ww2 souvenir from that area...that would make it a tourist piece...and would make me less happy

but the truth is the truth no matter how bad you want it to be something else.
