Think you may be on a bit of a sticky wicket, as they are secondhand, quoted vgc, not perfect & he covered his back by saying that he believed them to be Ducati Performance parts.
As to the weave of the carbon, DP have used more than one supplier for it's carbon products, so that would easly count for that. Also it is an auction, so you take your chances, I guess you can ask the guy, but for the price you paid you seem to have got a good deal. You could also put them back up on ebay & maybe make a profit on the sale
