Thanks Colford and waroff
The part is found at a terrain which was used as a huge scrapyard at the end of the war.
There were no other Mustang Mk.I, P-51/Mustang Mk.IA, P-51A/Mustang Mk.II or a P-51B/C crashes or losses in that area.
Do you have more information about F/O Parfitt's / Mustang...
Is it possible that this part belonged to a Mustang IA?
The part is found some miles from the airfield.
Are the (part?) numbers referring to this type?
