First comment, from Andy Dawson, as follows:
"There certainly look to be some Mosquito parts in there.
Picture 1 contains nacelles (one appears to have been cut for some reason so only the bottom half remains), firewall components and at least one undercarriage leg.
Photo 2 shows the cut nacelle with the undercarriage doors clearly visible, several main wheels, a couple of undercarriage legs and what appears to be the top of the pilot's armour plate.
Photo 3; not sure. There's a flap pivot in the centre of the frame (see
http://www.mossie.org/images/HJ711/l...-07-02_063.jpg and what look like tail wheel tyres.
Photo 4 shows main wheels and pilot's armour plate. Also the front of the cut nacelle's undercarriage doors."
It's looking pretty conclusive, I'd say! Now - if there are any identifying serial numbers or data plates it might be possible to identify the aircraft.
