I looked in completed gunbroker auctions (you have to sign in to look at completed ones) and I couldn't find either the Beretta or the browning Citori. As a seller you can't end an auction with bids. You can if you are selling with a reserve and the bids are still under the reserve.

When I've reported fraudulent listing to GB they are terrible about acting on them quickly.

Your best bet if you want to know what happened with these is to look in your internet browser history to find the listing and see if you see any feedback now for the seller.
