This Arabic closed well can be seen in various pictures and in many local variants. It was, and still it is, typical of Northern Africa (more specifically of Libya).

A.P. Models carefully studied available pictures and descriptions (also first-hand accounts of a person who lived in Libya) to arrange this accessory for desert dioramas.

The original pit well/is built in stones filled with mud or plaster and walls were/are thick enough to prevent evaporation of water and infiltration of sand.
