In the second photo, they're working on a swimming pool, for their own use. Wheelbarrow show in the rear to the right. The photo is wider, but I only found it cut across two pages of a magazine article here: German Sailors on the High Desert
Same wheelbarrows, probably; different projects. Early 1940s.

Jo's photo.
I know everyone in that picture—people from Australia and England who ate together in East Sussex yesterday.
Next to that photo, on the same webpage, was another wheelbarrow, all wooden, without notes, except the name "Chinese wheelbarrow." The details are nice. I suppose the rails and knobs are more than decorative, if a load could have been tied in or covered.
