Here's another photo, this is from a fascinating book "The Chariots of the Air" by Harold Hales published in 1938. This gentleman was an importer/exporter as well an MP who made frequent visits to the Far East. The book describes making the trip by air and contrasts it with his previous voyages by ship/train. Unfortunately the section on Rutbah (which he calls Rutbah Wells) is brief, saying only that they stopped there for lunch and fuel on a day's run from Gaza to Baghdad.
