Coff, India 42,
I'm sorry to say I never did have a photograph of the Barrels on the canopy rails. It must have been a memorable do though, I seem to recall we "put away" 6 x 88 pint firkin (I believe the 88 pint jobby is a firkin) in around 2 hours. That would be the UAS staff instructors, that days 6 AEF pilots and around half the ground crew (in all a maximum of fifty people). Like all things that are great memories, I so often failed to record them with a camera.
