I have a strange request regarding Britannia G-BDLZ of Air Faisal - this aircraft (ex XM490) was delivered to Stansted 30th October 1975 for civil conversion by Aviation Traders - it was rolled out of their hangar 4th December 1975 named "Al Mubarak" and with the airline titles incorrectly painted as "Air Faisel" (with an "e" instead of an "a") - it remained this way until at least June 1976 - as per photo below - I am trying to find a date for when this was corrected - if any of you have photos of this aircraft (and you know the date they were taken) could you please have a look as you may be able to narrow down the date a bit - Thank You (I am currently writing a concise history of Luton Airport and putting details against all the aircraft that were based at Luton from 1937 until present day)
