As always, The Amazing Karen come through. There's plenty of detail in the photo. Like almost all airfields in 1927, leBourget was basically just a big open field with no runways, or rather, an infinite number of runways. In the photo we can see administration buildings, a row of large maintenance hangars, and a row behind of smaller storage hangars. It's not a schematic but it would be easy to create a schematic from it. Good work!
