Ironically, in today's WT, JWs are encouraged to study the early history of the "earthly organization".
Well, this may seem like a new initiative but it ain't.
The Watchtower has periodically paid lip-service to the witnesses needing to know about the early organization such as in Russell's and then Rutherford's day. But like purveyors of snob-quality wine, the Watchtower insists you check the label before taking a sip: Keep away from "cheap" wine purveyed by the Apostates Vineyard.
In the 1950s, they published a very polished inside view of the organization entitled (I think) "Jehovah's Witnesses in the Divine Purpose" - an impressively presented A4 hard-bound book structured around a modern-day JW couple studying with a newly-interested couple. Of course it was a heavily edited and biased account of early Watchtower events. It had the newly-interested couple raising perfectly scripted questions about a number of "allegations" made by "opposers" against Russell and Rutherford. All questions were elegantly - and simplistically - answered. Spin has seldom been so superbly spun.
Similarly in the 1950s, crusty old long-time JW, Harold McMillan wrote a firsthand account of serving alongside Russell and Rutherford at Watchtower headquarters. Published by a famous worldy printery, Faith on the March became an American "best-seller" (don't be put off by the fact that most of the buyers were loyal witnesses!). My maternal grandfather gave me a well worn copy to read when I was only ten. McMillan's book was earthier and blunter than the Watchtower-published book mentioned above. McMillan was arrogantly dismissive about evidence against both deceased leaders and pretty damn scathing of anyone, especially "opposers" (i.e., apostates), who dared question the Watchtower's authority.
