OMG!!..You found Kurt Tank's last project smuggled out of Germany and sent to Pungo for research and reverse engineering!!
It looks to be the training version of the C152missile/rocket, codenamed "Cessna" by the Allies, and named "Blitzkreig Leider-hosen" by the Germans. It was only rumored to exist, as the war ended before mass production of the prototype could begin. According to some estimates it could hold as much as 37.5 gallons of rocket fuel and had enough payload capacity for 1 pilot and luggage!
Clearly the Allies did not want this technology to fall into the hands of the Soviets.
Obviously very advanced technology, even in the paint applied. It still retains it's camouflage paint scheme.
