Find the lockers

On occasion, I set myself little memory challenges. Today, the challenge was to recall the locations of each of my lockers in high school, and if possible the numbers emblazoned on each. I know I could walk to them, remembering the location from the end of the row (I did count them, back then). The actual locker numbers evade my scan. I do recall the combination of my Dudley lock. That was 22-51-9.
