This is the vestry, combined with the cathedral's massive organs. There are a couple of things to pick up here:
Use the chain near the keyboard to release the organs and through this act of vandalism neutralize the manticora (leo) outside and gain access to the brass lever.
Later, after you unlock the doors in the model room, head to the vestry to pick up the priest icon, documents, and use the brass lever on the protruding winch near the cogs to manipulate them into position (after shutting down the waterwheel below). Then you can re-enable the waterwheel and finally head to recover the grail.
