That second pic is of the plunge base #6931, so it definitely has both bases.  I would call/email him and find out what model of router he has as that base can be used for multiple models.   Looks pretty good, but if he has posted it 4 times with no luck, then make sure he lowers the price for you.  He says it's hardly used, but make sure it isn't rusty or anything like that as well.
