Incidentally, regarding the windshield, the Airfix clear part has a pair of faint lines which would tempt the unwary into painting them as part of a frame; now I am aware of this trap I shall leave them unpainted, or sand and polish them out, to be decided…
these two lines are the joint of 1/4"glasses and just behind, lined up to them there were the tie rods(3/16 dia) which maintain the top and bottom frame-

ssuming this is the case, which of the two holes in the glass (and therefore which filler cap)needs to be removed? I'm afraid I don't know which is the fuel cap and which is the oil cap...!
I haven't seen this feature in any other image of a P-40 (including RAF Tomahawks) so I am curious if it was a standard production fit, or perhaps a short lived trial.

Sorry, I'm wrong(fail memory) about the fuel cap on early P40 , Dana give the good response, fuel cap was on fuselage just below the port rear window

Effectively, there were no vertical frame
On P 36 and P40, up to P40C, the windscreen was an assembly of three piece of non shatterable glassmaintained together in top ans bottom frames assembly by two rods screwed.
the joints between the glasses were filled with glue.-

I would add wing guns (one per wing) had their ammo access on upper surface of wing and fuselage guns were long model(the short type
was made by cut off the forward end of these tube at a 25° angle, from 7th jul 41) and there was one hole only in the rear window for fuel cap,
the oil cap acces door was on the frame aft the glass-

the guns are aligned according the convenience of place in the wing. they are not on horizontal plan nor in the airfoil chord

link above, where you can see several other pics of "80" at different period and others french F5A and B.
the number and color of mission markings , "camera stylized", were different also.
at the beginning there were 9, in single color(red, black?), then these 9 symbols are painted in blue/white/red and there are 5 halves added, at the last the amount was 15 entire symbols b/w/r.
may be these last markings where added especiallyfor photo reporting on St Ex
is " Jeanne" added by the french or written by U.S crew , unfortunately on the pic the engine mask this nacelle area but there was not the dark crossed markings below the "80"-

their location was not the same depending on the model;
Sometimes the red light was near the bomb door -
MS 405/406 , 1937/38 (EMM MS 406, finish)
ms 405 / MS 406 received kaki on upper surface and gris bleu clair on under surface.the delimitation between kaki/gbc is straight along the bottom fuselage longeron from wing trailing edge to stabilizer leading edge
38-39
, the délimitation is wavy (short wave) (MS 405 seen at Chartres)MS 406: dec 39, a nota was introduced(MS factory camo & markings drawing):
upper surface will be received gris bleu foncé and brun(chocolate) blotches over the kaki. the delimitation of colours was blended by overspraying
delimitation with undersurface bris bleu clair was straight.
these blotches must be differ from an airplane to other.-

Don't forget that the nose is bent to the left and that reduction gear housing returns the prop and spinner back to paralel with the centreline.
the reduction gear is straight, the prop axis is parallel to centerline engine, so the axis is 1° left-

the offset asymetric airfoil was used also on french MS 540 project and on swiss D 3802/3 build.

the midnight blue was used for cockpit interior only(between frame 3 to 5 -from instrument panel to the backrest),
Under the rear vision windows the area could be painted gris bleu clair
or "natural finish", (duralumin sheet was coated with clear varnish on both side before assembly).
