Located at a workshop just outside the airport (the fence in the background is the airport perimeter). I didn't immediately recognize the type of aircraft and the people working there didn't know either. Thankfully, the editors here were able to help me out (thanks Aad & Peter!). The body was identified as being from Aerocomp, but there is a noticeable lack of attachment points for wings and engines. There are also 5 windows visible, where the original Jet had 4. That makes it likely that this is a mockup or new concept for the Aerocomp Jet aircraft.

A nice find and new type for my vocabulary. Now resident of what I can only describe as the corrosion corner of the airfield.
