Thanks Spiral....good call....you certainly seem to be in the right area
I found two images of 'full sized' masks from that area....not identical to those on the 'phurba' but demonstrates similarities... On the picture below them I've indicated where it feels comfortable to hold (just feels right ..and 'rub marks' seem to confirm this) Feels more like a Phurba 'sword' or 'spear'...than dagger.
Tim I will try and post daylight pics soon, (if the rain stops
) Very intriqued about this piece...cannot seem to find a similar sized one anywhere on the web.....
