Why the white exhaust stains?
Every other picture I can recall that shows exhaust stains flowing back are black, dark grey, but I've never noticed white before.
Or is the original photo B&W, and somebody messed up when they colorized it?

Likely mess up when colorized.

When I did a quick check on this, I ran across more with white exhaust stains.
What i ran across also is this: White exhaust stains on a P-39, especially near the tail section, are most likely due to lead residue from the tetraethyl lead added to the fuel. The high-octane fuel used in these aircraft contained tetraethyl lead to improve engine performance, and some of the lead would deposit on the fuselage as the exhaust gases cooled. The white stains are a result of this lead residue, sometimes described as "white chalk".

In 2004 P-39Q serial number 44-2911 was found in Lake Mart-Yavr, above the Arctic Circle in Siberia. The Airacobra had suffered an engine failure and crashed into the lake on November 1944. The remains of pilot Lt. Ivan Baranovsky were still inside. The aircraft is currently on display at the Niagara Museum of Flight, near where it was built.

Note the lack of stain on fourth aircraft, may be behind #3 fin/rudder, however I like to think a diligent crew chief cleaned it off.

Don't have to be awesome if there is a multitude. An oppressive crush of mediocrity followed by a multitude of good designs is obviously a winning strategy.
