Marine navigators have used the 2102-D star finder for many years as an aid to planning sights or identifying stars. The U.S. Air Force developed a variation in the mid-1950s called the CP-300/U that incorporated a number of useful enhancements.
I wrote this article some years back for the “The Navigator’s Newsletter” History of Navigation column (Issue #77 Fall 2002 pp.6-12) but no one seemes to have ever heard of this device or know what it fate was. Perhaps someone here has additional information.
