O.K., folks, I knew the answer from the beginning and here is the solution to the riddle:

This was a scam. The seller stole the pictures. As I was told by a person from the Russian sword Forum ( and these buggers know every Russian blade on the market, Lord bless them!), the original sword was sold 5 years ago to the Museums of the Moscow Kremlin for $100, 000. You see, Ivan Boyarshchinov's blades are worth their weight in gold. Finding a real, signed Boyarshchinov's sword is like finding the real Sword of the Prophet Mohammed with his personal autograph and affidavit from Allah himself.
The Indian dagger was just a bait, to establish recent positive feedback on an otherwise dormant ( highjacked) account. Now, some drooling jerk will transfer money to an one-time-only bank account and wait for the delivery. I suspect that this sword will be relisted in a week ( after the payment had been withdrawn) and the same sting will go on.
I think the scammer is the same one who perpetrated an identical scam ( 3 listings in a row!) about 3 years ago. I still remember the phraseology: don't ask me about the origin, Paypal only if < $700, Ukrainian source etc.
Unfortunately, we cannot warn the "buyer": private sale....
