I'm pretty sure that this is not a Mk IId, but is one of the three Mk V's built- they were all converted Mk IV's, and had an uprated Merlin 27 or 32 driving a four bladed Rotol Spitfire prop and spinner, along with a larger armored radiator. Not proceeded with, they were all converted back to Mk...
I think you meant portside for the circular device, as seen in the posted photo? If so, it appears to be a E-2 warning horn used when the throttle was retarded and the landing gear was still up. See the photo.

Not really sure, and this is just a wild guess, but I seem to recall that the ADI system was very hard on an engine when selected, and there was a limit on the amount of time that it could be used; at which time the engine had to be inspected for damage. Perhaps this is a 30-second timer used to...
Since that second oil cooler intake is below the oil cooler matrix itself, it might be there to create a venturi effect to enhance the extraction of the hot air from the oil cooler?

That's what I have read, as well. An 18 inch extension was added to each inner wing to allow space for additional wing fuel tanks; the wingtips were squared off, as Thomas stated, to improve the roll rate; IIRC there was an autopilot fitted to relieve the pilot on long flights as well as...
It might be a Bristol Perseus or Mercury radial; the Mercury was used in several aircraft, including the Skua, Blenheim, Bolinbroke, Martinet, Master, Sea Otter, Fokker DXXI, and Lysander. Best I can do- sorry!

You probably have seen these already, but if not, they do show some good modeling details and camouflage demarcations; as you have discovered, not a Mustang variant that was captured in very many photos. I have been slowly working on a 1/72 model of FR409, using a P-51D and P-51H kit, and some...
Very interesting! Going to take a wild guess here, but I think it might be Brtitish, as the font style of the serial number doesn't look like a U.S. style. It might be from a Lockheed 049 Constellation, as they used three blade props and airlines in Europe and the UK flew them. Too bulbous and...
According to data on the B-25 History website, the Mitchell in the photo might possibly one of the 200 Inglewood built B-25G-5NA's; that batch had serials from 42-64902 to 42-65101.
I'm not so sure! It looks more like an OA-12, J2F-5/6 to me! Look at the cutout for the center instrument on the top row and compare to the Stearman photo. I could be wrong...and often am!

Does this affect the other B-17's registered and flown in the U.S.? I was not aware how few airworthy B-17's remain here, and I am guessing Sally B in the UK is the only other one in the world. As much as I love seeing and hearing them fly at airshows, we might be getting close to the time that...
