I am so sorry OP, I think you have been sacmmed. I sent email to the SAME seller to take the picture of the bag with her ID and the date to proof the bag in her possesion, but she never replied. The problem with O feedback seller is they normally have a problem with their paypal account, I always emailed them first about the payment method prior to bidding whether their paypal ready or not.
The stolen picture is not the only problem on ebay, I once got scammed by the seller with 0 feedback also, (and ALSO from Sydney), She actually have the real vintage jumbo in her possesion, she sent me the pictures of the bag and her ID and the date, and I paid immedietly via paypal, but then 2 days later she claimed that paypal account is not ready etc, but later I find out that the bag in her possesion was belong to the rental property, she was actually scamming people from using rental bags. So be very careful about buying from the new seller, I would ask million questions and if you are satisfied with her answer than you can pay via paypal through CC just to be safe.
GOOD LUCK OP..
