I don't know how many times I have told people that this is a NEW kukri with marks copied from an authentic WW I piece. Since this guy is attempting to sell it as the real thing, I can call it a fake. If he professed ignorance, different story. These are just a figment of someone's imagination and not even a reproduction or copy since there never was such a military kukri.
You might want to ask him what makes him believe that a knife that is supposedly 86 years old could look so new and why he thinks it is authentic. Ask about the neccesary marks on the scabbard or what type leather it is, etc., etc. You might also ask how he came up with the amount of 'gold' on it. Unbelievable. Then again your questions will probably make him very defensive and you would get into an argument that isn't worth the time. He appears to be a new seller, so maybe he really does think it's the real deal but anyone who pays 1/10th what he's asking isn't getting a good deal.
EBay like anything you buy deserves a goodly amount of CAVEAT EMPTOR.
