  1. XIV had id lamp under the fuselage between frames15/16 and under each wing between ribs 18/19 it's similar on mk VII & VIII. when there was only one downward id lamp under the fuselage (or the wing on the Mk VIII early), the amber lens could be replaced by red or green lens as purpose required
  2. Thank's Dana, I agree that it's impossible to obtain the same effect on the model, the haze paint was as a polarizing filter over the undercoat which cut some radiations according the light incidence. the render is different depending the light and the watcher position if I understood correctly.
  3. There is one chart, white, red, blue for insignia and a second chart showing the reflectance of 4 shades of haze on undercoat, black to white, graded tone on side surfaces. I understood it that way.. I think that lower sides no need black undercoat because these surfaces don't receive direct sun light
  4. According this Lockheed"s drawing(april 42), there was a white undercoat at lower side. On this drawing, the uncoloured surfaces is black and dark for the white or I'm wrong.
  5. the haze blue finish require a black 44 undercoat at the topside and white 46 at the underside, the graded delimitation between these two shades is on large area. Then haze blue paint was sprayed to obtain 8% reflectance on the black to 45% on the white measured with photometer. The lower insignia receive as much paint as underside.
  6. the prop blades are similar Drawings , R12/4F5/4 for Seafire III and R3/4F5/3 dural or R3/4F5/4 hydulignum for Mk IX
  7. To see the camera fairing under the wing and the identification light under the right wing fillet, this is an E-1. E & N1 hadn't reco light and N-5 & subsequent had 3 downward lights, 1 in the rear of keel fairing and 2 in the rear fuselage. N hadn't electric tab built in the port aileron but a single tab which protrude the trailing edge identical as the starboard side. It's possible that Pitot tube is cranked but not easy to see on this picture.
  8. There is also the tail wheel bulge on P36, the diameter of this tail wheel is smaller(10" instead 12.5), diameter of main wheels is 27" instead 30" and the cutout of stabilizer/elevator is more forward. The headrest, the keel fairing are different.

    Tomahawk IIA Query

    it's not easy to see the pattern on port wing because the incidence of lighting is bad Below, the roundel applied by Curtiss on H81 and H87 allocated to british. comparison of ratio of red dia (white: Curtiss and red:RAF) the main plane is build from two wings which are bolted together in center line

    Tomahawk IIA Query

    the roundel on port wing was the roundel decal applied at curtiss factory which has 47" diameter for the blue and 15"3/4 for the red. So if there was a replacement or repair, it was the starboard wing
  11. in "Spitfire Mk VIII, AP 1565H" it is wrote in several chapter: "2 - A camera gun is mounted in the leading edge fillet of starboard main plane" "43 - A G-45 camera gun is mounted in starboard leading edge fillet, and is pneumatically operated by a puh-button on the spade-grip..." The loadind & CG diagram show G-45 camera and give the weight: 8.5lb
  12. JF xxx serial and engine(4th column) : http://www.airhistory.org.uk/spitfire/p045.html http://www.airhistory.org.uk/spitfire/p046.html M61, 63and 63A had fuel cooler and coffman crank case M66 and M70 had'nt the coffman crank case, so it's not sure that starboard engine cowling had the bulge.
  13. Spit F VIII powered by Merlin 61, 63 or 63A had fuel cooler. On LF(M66) and HF(M70) not need fuel cooler, the aperture in port wing fillet receive a cover plate. On all Mk VIII the G45 camera was fitted in starboard leading edge
  14. Tomahawk could be fitted with two seat types. rounded, the mounting is slightly bent at the top just before the armour plate and the squared type, there was a cast part bolted on armour plate the harness was a Sutton K ( eyelets on lapbelt).
  15. Trumpeter size the cockpit for chinese pilots which had short legs..... Sutton

    Spitfire Gun Camera

    And the G22 camera, just aft the front spar, between rib 4 & 5

    Spitfire Gun Camera

    Or closed with a cover plate
  18. the filament lamp is standard with clear glass under a coloured lens. In this case the fairing is clear. In the case of coloured fairing there is not a lens over the bulb.

    Spitfire Gun Camera

    earlier Mk I, on the starboard, mounted at top of wing it was a G22 (camera gun, single exposure at each time the button is pressed). On Mk I & II, a G42B then G45 (cine camera gun,)was fitted in the leading edge of port wing. The camera mounting was on the rib 1. On the drawing, the rib 1 is drawn horizontally so the c/l camera is down( in reality, the c/l is ~parallel to c/l aircraft)

    P-40 help

    Since oct 42, P40s had a possibility to change the color of tail light(nav light) to identification purpose. When used as navigation light the lens is clear frosted. When required as identification light, narrow beam "resin" lenses, red; green or clear replace the standard lens on each side. There was a lens stowage box installed in the fuselage to receive the unused lenses. The cable of tail lights was disconnected of its junctions with wing lights and was connected to a new dimmed circuit.
  21. Mk VIII sight, according the pilot's flight operating instructions D-25 up to D-35 and british models
  22. US ARMY lettering( insignia blue color) seen on P40 and P40B&C the rudder balance weight was in the rudder leading edge or in the horn at the top. What you can see at the left of rudder was not a counterweight but the top hinge
  23. On the AVG's p40B, the chinese insignias had different rays and different space between the rays. these insignias were probably painted. for the P40E allocated to China, the chinese insignias were decals purchased from Di-Noc MFG. The blue was "Dark Curtiss Blue No 1262"(1942, paint) or "No 1282"(1943, decal Curtiss ref 464) Is these two shades are variations of this Curtiss Blue 1263 below? (darker or lighter?) source: aviationofjapan.
  24. the vertical angle of leg pintle was 17°30 on early models, to 20° on later models, so the wheel well was inclined Best wishes!!!
  25. Hello Hume, how are you? in the right rear window it's the cap filler of de-icing tank which is behind the headrest armor plate. "An opening is cut on the right-hand side of vision glass to allow for the filling of the anti-icer tank. This opening is fixed with a hinge cover operating from inside.", this change sept 1942 Merry Christmas !!! Edit: the propeller anti-icer tank is between Sta 7 & 8 on P40E (and Sta 5 / 6 on F, L, K & M when fitted, on these models, the cap is just behind the frame Sta 5)
