Schluter Heli boy still in box.

I have a Heli-boy system 80 that was purchased in 1978 for around $1000. The helicopter has been put together except the body is still in the box and needs to be cut out and painted. The original owner had the motor balanced and had an aftermarket pipe put on. This heli has never been run. It has a Kraft sport series remote that is in original box. All instructions are in German. Looking for a collector to pick this up.
