babnik, it is a bit confusing at first, even reading the descriptions. Rest assured that within a year, your eyes will know what to look for. I can't remember actually learning... it just became clear. When in doubt, just don't extract that frame.
It was all there with the exception of the queen cell, I robbed it from another hive and used this frame in a trap out. The queen cell is pinned in place with a frame nail, if you look hard at the top of it you will see the head of the nail.
