Ok here are the pictures. The first picture is all of them. The one at the top of the first pic is the defect, the 2 that are together are the new ones and the other 6 are the used ones. The pic of the back of the faucet is where I believe is too much plating on the teeth on the inside.
As for brand I have no idea.... All the used faucets have less than 1 batch each poured through them. Hope this helps.
