As with almost anything historical relating to the Watchtower, this information is incomplete in official WTS publications. With the exception of KNs 1 through 3, which the WTB&TS seems to be very proud of, issues up to 1946's number 15 are hardly mentioned at all - some not at all - and most of the early KNs are not reproduced in any current WTB&TS publication. What glorius Bible-based Light© are they hiding?
