Martin,
the little scoops visible in your excellent photo (!!!) seem to bear out earlier mention that the scoop was from a P-51D. IIRC, the B/C radiator fairing does not have these vents. I was wondering how much the D fairing had to be modified to make it fit the shallower wing/longeron arrangement of the earlier types? Corrections/clarifications requested!
The little scoops must be from a very late D as the D's I take care of do not have them. Those are the inlet for the fuel tank vent system. Those allow the fuel tanks to breathe. If the air isn't able to flow in to replace the fuel used the engine won't run very well. That area of the airframe is exposed to high pressure which acts to pressurize the fuel tanks to a degree. The little scoops would enhance that.
