An early adjustable jaw, adjustable angle nut wrench. The jaw is adjusted by a threaded bolt; the angle between the handle and head can be changed by opening spring-loaded pawls on the handle that engage notches on the base of the head. A turn-button on either side of the handle can hold the pawl on that side "open". The specifications note the adjustable jaw feature is optional, but do not mention any ratchet action with the pawls.
