Possible Taiwanese Aboriginal Shield???

[drac2k]

After reading a recent thread (I believe by Resword ), on "Taiwanese Aboriginal Shields," I remembered a collector who had a pair.When I first saw them, they only held a modest interest , however after my forum induced education I went back and asked him if he was interested in selling them to me .The lesser of the two, he sold for a very modest price, the other, he stated, while grinning, we could do a trade; that may prove to be very difficult !
Based on my reading of the article I believe this to be a Paiwan shield, the black and white triangles representing snake scales, the figures, deities.I believe this to be a ceremonial or tourist piece as the handle configuration doesn't look to be combat worthy, and there is no flex to the shield as there are 4 internal metal pieces (the thickness of nails), holding it rigid.Also it doesn't look to be terribly old; this being said it is not new and you can see traces of marks where the boards were planed by a knife like instrument.
Any comments on this item would be appreciated !
