Judging by this photo, it seems that G-AGLS didn’t have any stripes beneath the registration, atleast on the fuselage sides. I can’t find any shots clearly showing the reg on the wings.

On the subject of Lancastrians, does anyone know if there have been any more expeditions sent out to the crash site of “Stardust” since the one featured on TV a few years ago? Are there likely to be any more?
