I believe that hook it is off a Cletrac 7 ton high speed tractor. These tractors were built for the US Army Airforce and were fitted with two tow hooks at the rear, the quick release one as in your photo and another similar to the standard ordnance pintle.
A release cable passed around the pulley and went up to a lever mounted behind the drivers seat so as the towed load could be dropped off without having to dismount from the vehicle.
