Help identifying this keyway

[approachesinfinity]

the key to my dorm has always interested me; i know its an interchangeable cylinder but i can't quite identify the keyway

the lock in question is a schlage L series i think.

here's a picture, any help would be appreciated (this has been bugging me since august)
