There are four pieces on a7, c7, g7 and h7. What are they?

There are four pieces on a2, a8, c7 and h8. What are they? What was the last move?
Additionally we know, that pieces that are still on their original squares have not moved during the game. Also, no piece has returned to its original square during the game.
edit/RT: this includes the Black knights and a1-rook, you can assume they have not left their original squares.
