This one late 50's, if it helps, 'twas Airwork too but under the tailplane in very small letters B.O.A.C. could be seen.
My flight log records this journey:

I still retain the original Flight Information sheet, the pilot was Captain Talbot, Air Hostess were Miss Adams and Miss Irwin we were then (on issue of info) at Zakho on the Turkish/Iraq border at a height of 11500 feet 205 ground knots 236 MPH
I recall Basrah being extremely hot even in February and at that time of the day too. I'm fairly positive that the engineers wore white overalls at our staging stops and that the passenger steps were in BOAC livery
