Well Tim, ww1 & ww2 kukri certainly turn up on ebay & through dealers, but cheaply is not always the case!
Intrestingly the modern Indian fakes of the Mk.2 style, normaly dated 1917 & with inspector stamp "37" with brass handle fittings quite often seem to sell for more than the originals
I guess they are often shiney though
.
As long as an item is handmade {at least partialy} & in an ethnic style , I percieve them as ethnographic.
If made in thier ethnic area by machine for locals ,I percieve them as ethnographic.
If made in thier ethnic area by machine for export,I percieve them as commercial, semi/almost ethnographic.
If made in a non ethnic area by machine for sale to non original ethnic people,I percieve them as commercial copies, non ethnographic.
