He he he he he. I just got my hands on a book from 1959: Jehovah's Witnesses in the Divine Purpose.
Here's a little snippet from Chapter 9, which is entitled "End of All Kingdoms in 1914":
Tom: When 1914 finally arrived and the first world war began, I suppose Jehovah's witnesses really came into their own, didn't they?
John: Not exactly. For the first few months of the year the religious leaders and others were pouring considerable ridicule upon Russell and the Watch Tower Society, because in those early months nothing had happened to the Gentile nation as Jehovah's Witnesses had been expecting...
John: It was, although there were many things taking place that the Witnesses themselves did not realize. For forty years prior to 1914 they had been pointing to this date through Scriptural developments. Now as factual evidences began to appear to verify the conclusions they had reachedd by this Bible study, they were certain that October 1, 1914, brought a legal end to the 2,520 years of Jehovah's tolerance of the sovereignty assumed by the Gentile nations over the earth; that legally the "end of all nations" had come in 1914!
There's even a "Chart of the Ages" on page 67. It's a little small, but one is still able to read it.

To demonstrate the League's dependence on Britain's backing, Brother Rutherford declared: "Let Britain withdraw from it tommorow, and it will go down immediately." In conclusion he described the blessings of God's kingdom.
And on 126:
You will recall that at the 1926 convention of Jehovah's witnesses at London, England, it had been declared that the League of Nations was the "beast" of Revelation 17:11 and that it was certain to suffer destruction at God's hands.
And about World Ward II, on 153:
As the Nazi-Facist-Catholic war drive stamped throughout Europe...
