I have a (translated in Dutch) Mary Blewitt edition from 1964. My first celestial book, that I bought in 1978.
There are 2 pages from the Air Alamanac for 6 jan 1964.
She mentioned that the Air Alamanac is printed for three different periods jan-april, mei-august and september-december.
Each period cost sh. 17/6.
She also informed there are other alamacs: The Nautical Almanac and the compact Reeds Alamanac.(disadvantage much interpolation needed)
This just for curiosity.
