What a great photo. Thanks for posting it.
blimey, you get led into the weird and wonderful on this thread
I have just learned that the US Army Air Force marking started as a plain red star, then it changed to a roundel for commonality with other WW1 allies.
That means the aircraft are not British or French as I originally thought.
So that makes the aircraft Curtiss JN-4s (Jennys) around 1918.
The hangars seem to match with this photo.
I'll go for it being Dallas Love Field (KDAL) just after America entered WW1.
