I remember the mischief in the "Chronology" article in the "Aid" book, such as half a sentence from Neugebauer (repeated in the "Insight" book), misrepresenting Pritchard's book, and so on.
Something I wrote about 1987 might be relevant to your question:
I wonder if "Scholastic Dishonesty of the Watchtower" is still around. It contains a letter from Mantey who wrote to the Watchtower demanding an apology for the way they were using his book.
I recall that they misquoted Hislop by using "the trinity" whereas he wrote "a trinity".
In the original NWT NT intro they showed a picture from Justus Lipsius of a man tied to a pole, without revealing that this was only one of many pictures in Lipsius' book (De Cruce Liber Primus) and that he concluded the conventional depiction was the correct one.
Page 134 of the 1963 book, "Babylon the Great Has Fallen!" says that page 306 of "Harper's Bible Dictionary" says Nebuchadnezzar came against Jehoiakim in 618 BC, but the Dictionary says that Jehoiakim was dethroned in 598 BC.
The WTS repeatedly cites the book "Babylonian Chronology" by Parker and Dubberstein as being the authoritative source, yet the WTS does not accept the dates provided by P&D.
