Sadly I no longer have this axe or the pics. Indian stuff never stays long with me. In this link the black and white pic shows a similar upside down type of axe head. This type of axe is often described as rare by some collectors and dealers so it might be a good idea to make a sensible offer, 2-3 of ponies?
