The three on the right are the different styles. The top is just like the other "castles?" in the pic. The difference in those is on the bottom, some have deep cups, some shallow, 1 has no cup at all. The middle is a crosstop where the indentation goes all the way to the hole. That's the only one of those, it has a deep cup. The bottom right is a match to the other 6 sidetabs, except for 2 of them, which have much deeper cups on the bottom.
