They all seem to be genuine, the first one is a few years newer and made in Costa Rica, the others are made in the US. I'm wondering if the front flap on the third one is a bit crooked, it seems like it's higher on the right side unless that's just the way the seller stuffed the bag for the photos. There have been quite a few fake Willises on eBay. The creeds and turnlocks are sometimes a bit "off" but it's still best to ask here for authentication. Never bid on one unless the seller is showing clear pictures of the creed stamp.
