Help us find a Stray HS-748 Instrument Panel.

Hi all
I have attached a photograph of an Engine Instrument Panel from HS-748 G-OJEM. My son Max has both the pilot’s and Co[pilot’s panels, as well as a few other small overhead and side panels from this aircraft.

The Engine Instrument Panel however, slipped through our fingers and is in the ownership of an unknown collector. We would very much like to reunite it with the other panels if at all possible. All we have from the previous owner is this photograph! http://i235.photobucket.com/albums/ee38/_aida_/Max1.jpg

We would be willing to either buy it back or offer a seat on an engine and taxi run in our Jet Provost Mk.3A, XN584, at Bruntingthorpe in exchange if it was available to us.

Any help would be appiciated.
Thanks in advance.
