There is one Ebay dealer here in the USA and one dealer in the UK who consign from the same source in Russia fakes, reproductions, and married pieces and sell them on Ebay as originals. It is interesting that when they are challenged, they come up with either a no return policy as the items are being consigned from Russia and the consignor is to remain Anonymous or the item has a life time guarantee of authenticity, however, it is you who has to prove otherwise by some testimonial letter from some expert from a Russian Museum in Russia. DON'T THESE STATEMENTS MADE BY THE SELLER RAISE SOME RED FLAGS AS TO WHO YOU ARE DEALING WITH ???
