Where's the full pic? Maybe I can image search it and get something bigger.Here is another photo. An enlarged detail from a 1933 photo.
Look at the epaulettes of the standing man with light coloured cuffs.
This was the(?) Advanced Aviation Training Unit (edit: "Avigation" - see just below), ie, hot pilots and those who showed promise to be same. Can't find much reference to it tho.It would be a huge help if we knew who the crew/unit were in the 1933 picture, top brass or regular Joes? Re post #124
It's in just the right place for one!
