Merci à tous pour vos informations. Le cas de la camera et du système de refroidissement a l'air clarifié.
Le cas de feux d'identification a l'air un peu complexe. J'ai trouvé ça sur un autre forum:
used entries, under "Authority - Air Ministry," in the Vickers Spitfire/Seafire mod ledger, as definitive dates for production, but they are the dates of relevant minutes in meetings of the Local Technical Committee. There is another column, headed "position," which contains wordings, like "Cleared," or "Cancelled," and these seem to be more likely for the dates of introduction (or otherwise) onto the shop floor.
746's full wording is "To delete red and green down-ward recognition lights on wings," and is listed for the VII & VIII; the "Cleared" date, together with "Drgs & P.M.S. issued," and "Included in Mk VII & VIII D.I.S." is 1.5.43 (don't forget U.K. dates are written in the reverse of those of the U.S.)
989's wording is "To introduce two additional downward identification lights (red & green)" and was cleared 7-12-44 (very late, which probably explains why photos are so rare) for the VIII & XIV only.
If modifications were possible, in the field, leaflets were usually issued, for the workshops; no leaflets were ever issued for 746 or 989, so they were strictly in-house.
The "extra" amber light remains a mystery, since I can find no mention of it, but Rolls-Royce's XIV RM689 has its lamp fitted in that position, so it isn't totally impossible; jury's still out, on that, I'm afraid. It's possible that it was to do with the projected use of the fuselage tank, or that of the "torpedo" droptank, which was trialled in early 1944, and might have blanked-off the original light.
Du coup, quid de ces deux appareils ? Lampes vertes et rouges ou pas ? Ca ne paraît pas simple de trancher
Est-ce qu'il n'y a pas des questions autour des antennes radio également ?
Pour les feux, on sait que les avions livres aux americains et utilises en AFN et Italie en etaient equipes, et ce sont des avions de Fevrier/Mars 1943, ce qui est donc coherent avec la date the retrait theorique des feux.
J'en suis meme venu a me demander si le retraits des feux a ete effectif vu qu'on trouve des avions produits bien avant le 7-12-44 et qui semblent encore avoir les feux sous les ailes
