Handy for finding out if some planet or other is visible between the trees that mostly block my south view. I always thought you would have to be in pretty dire straits to need to use one of these. By way of confession, the bottom half got made into a harmonograph about 55 years ago.

And the Astro compass with suitable charts for night navigation. It was a big thing with the RNZAF during WW2 flying Hudsons / Ventruders, and DC-3/C-47s up the Pacific, often escorting a squadron Of P-40s or Corsairs over thousands of miles of open sea to a pin point Island airfield. Also used on the Catalinas and Sunderlands on patrol. Ian S C
