This building paper model is an Airship Mooring Mast (Mooring Tower), created by Ralph Currell. The scale of the model is in 1:700. A mooring mast is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure.
When it is not necessary or convenient to put an airship into its hangar (or Shed) between flights, airships can be moored on the surface of land or water, in the air to one or more wires, or to a mooring mast. After their development mooring masts became the standard approach to mooring airships as considerable manhandling was avoided. More information of the mooring mast at wikipedia.
