In the smithy there are no new armor (Assassin's Creed: Brotherhood)

In short. I'm already on sequence 4, and is still in the forge, no bib, walk like a goof with 7 squares HP... Was that in the forge suddenly appeared the best armor (which you can buy), although it should open closer to the middle or the end of the game. In the forge not just a new armor, what to do?
