Frank you wrote: Actually my guess, for now, with no real evidence, is that these were charts prepared for visual satellite trackers in the 1960s as part of "Project Moonwatch".
Of course, the figures on the left are hours and minutes. If we were sure there wasn't too much missing between the ends we could find the period and hence the orbital height and speed. Knowing the tilt as well, about 31 degrees, we might be able to identify which satellite we were supposed to be observing. DaveP
