For those of you who are interested, here's a summary of what the Society had to say about the The Finished Mystery in the Revelation Climax book:

"As early as 1917, the Watch Tower Society published the book The Finished Mystery. This was a verse-by-verse commentary on the Bible books of Ezekiel and Revelation. Then, as world events continued to unfold in fulfillment of Bible prophecy, a timely two-volume work entitled Light was prepared, being released in 1930. This offered an updated study of Revelation. Light continued to ‘flash up for the righteous,’ so that in 1963, Jehovah’s Witnesses published the 704-page book “Babylon the Great Has Fallen!” God’s Kingdom Rules!"

"What John sees foreshadows remarkably the experience of the John class at the beginning of the Lord’s day. Their understanding of Jehovah’s purposes, including the implication of the seven thunders, was then incomplete. Nevertheless, they had a deep interest in Revelation, and Charles Taze Russell had commented on many parts of it during his lifetime. After his death in 1916, many of his writings were collected and published in a book entitled The Finished Mystery. In time, though, this book proved to be unsatisfactory as an explanation of Revelation. The remnant of Christ’s brothers had to wait a while longer, until the visions started to be fulfilled, for an accurate understanding of that inspired record."

"The fact that they were described as two witnesses also reminds us of the transfiguration. In that vision, three of Jesus’ apostles saw him in Kingdom glory, accompanied by Moses and Elijah. This foreshadowed Jesus’ sitting down on his glorious throne in 1914 to accomplish a work prefigured by those two prophets. (Matthew 17:1-3) Fittingly, the two witnesses are now seen to perform signs reminiscent of those of Moses and Elijah. For example, John says of them: “And if anyone wants to harm them, fire issues forth from their mouths and devours their enemies; and if anyone should want to harm them, in this manner he must be killed. These have the authority to shut up heaven that no rain should fall during the days of their prophesying.”—Revelation 11:5, 6a."
"This reminds us of the time when Moses’ authority was challenged in Israel. That prophet uttered fiery words of judgment, and Jehovah destroyed the rebels, consuming 250 of them by literal fire from heaven. (Numbers 16:1-7, 28-35) Similarly, Christendom’s leaders defied the Bible Students, saying that these had never graduated from theological colleges. But God’s witnesses had higher credentials as ministers: those meek persons who heeded their Scriptural message. (2 Corinthians 3:2, 3) In 1917 the Bible Students published The Finished Mystery, a powerful commentary on Revelation and Ezekiel. This was followed by the distribution of 10,000,000 copies of the four-page tract The Bible Students Monthly with the feature article entitled “The Fall of Babylon—Why Christendom Must Now Suffer—the Final Outcome.” In the United States, the irate clergy used the war hysteria as an excuse to get the book banned. In other countries the book was censored. Nevertheless, God’s servants kept fighting back with fiery issues of the four-page tract entitled Kingdom News. As the Lord’s day proceeded, other publications would make clear Christendom’s spiritually defunct condition.—Compare Jeremiah 5:14."
So, despite the fact that The Finished Mystery was "unsatisfactory as an explanation of Revelation", the mere fact that it was "a powerful commentary" (a controversial book that the clergy tried to ban on grounds of creating war hysteria) meant that it provided the fulfilment of the scripture in Revelation 11:5,6 foretelling the "two witnesses". In essence, a book that did a crap job of explaining Revelation ended up fulfilling it?!

"The public press joined the clergy in vilifying God’s people, one paper saying: “The finis of The Finished Mystery has been given.” Nothing, though, could have been further from the truth!The two witnesses did not stay dead. We read: “And after the three and a half days spirit of life from God entered into them, and they stood upon their feet, and great fear fell upon those beholding them. And they heard a loud voice out of heaven say to them: ‘Come on up here.’ And they went up into heaven in the cloud, and their enemies beheld them.” (Revelation 11:11, 12)"

"In his book Preachers Present Arms, published in 1933, Ray H. Abrams refers to the clergy’s bitter opposition to the Bible Students’ book The Finished Mystery. He reviews the clergy’s endeavors to rid themselves of the Bible Students and their “pestilential persuasion.” This led to the court case that resulted in sentencing of J. F. Rutherford and seven companions to long years of imprisonment. Dr. Abrams adds: “An analysis of the whole case leads to the conclusion that the churches and the clergy were originally behind the movement to stamp out the Russellites. In Canada, in February, 1918, the ministers began a systematic campaign against them and their publications, particularly The Finished Mystery. According to the Winnipeg Tribune, . . . the suppression of their book was believed to have been directly brought about by the ‘representations of the clergy.’”
Dr. Abrams continues: “When the news of the twenty-year sentences reached the editors of the religious press, practically every one of these publications, great and small, rejoiced over the event. I have been unable to discover any words of sympathy in any of the orthodox religious journals. ‘There can be no question,’ concluded Upton Sinclair, that ‘the persecution . . . sprang in part from the fact that they had won the hatred of “orthodox” religious bodies.’ What the combined efforts of the churches had failed to do the government now seemed to have succeeded in accomplishing for them.” After quoting the derogatory comments of a number of religious publications, the writer referred to the reversal of the decision in the Court of Appeals and remarked: “This verdict was greeted with silence in the churches.”"

"Thus, rather than following the example of faithful Peter, these and other popes were an evil influence. They allowed bloodguilt and spiritual and physical fornication, as well as a Jezebel influence, to corrupt the church they ruled. (James 4:4) In 1917 the Bible Students’ book The Finished Mystery set out many of these facts in stark detail. This was one way that the Bible Students in those days ‘struck the earth with every sort of plague.’—Revelation 11:6; 14:8; 17:1, 2, 5."
I think we can all agree that The Finished Mystery was many things, but a book of "facts" was not one of them!
