Glad the Filton AF guys enjoyed their Concorde fix. (There is no other Concorde in the UK, bar none, that able to achieve this fix better than G-BOAC can
). As far as the gear door colours go, well the 'normal' colour is the light brown one that you describe, the green primer colour door is a replacement one. (As to when we did that replacement I really can't remember I'm afraid - Extreme Brain Fatigue
).
I'll have a closer look at that door when I'm next up in Manchester in 10 days.
Best Regards
