Wndsn Universal Moon Clock

Wndsn universal moon clock; the view from the northern hemisphere from the front, and the view from the southern hemisphere from the reverse side. Yes, it’s one and the same device, seen from the transparent, and hence mirrored, backside. Up is down.

A visual aid in determining Moon phase, we introduce a simple universal equatorium predicting cardinal direction, and approximate time (in unequal hours) from observed shape and altitude in either hemisphere. Made in Germany.

This is a teaching tool showing average (equinox) conditions; the directions and times throughout the rest of the year have to be extrapolated.
