Assertions about spirit-directed, scriptural 'evidence' and 'facts' concerning the identity of the FDS over the decades:
2012 AGM
The evidence points to the following conclusion: “The faithful and discreet slave” was appointed over Jesus’ domestics in 1919. That slave is the small, composite group of anointed brothers serving at world headquarters during Christ’s presence who are directly involved in preparing and dispensing spiritual food. When this group work together as the Governing Body, they act as “the faithful and discreet slave.”

The facts indicate that this faithful and discreet slave class comprises all anointed Christians as a group on earth at any given time.
w81 3/1 pp. 24-26 Do You Appreciate the "Faithful and Discreet Slave"?
Witnesses of Jehovah understand thatthe "slave" is comprised of all anointed Christians as a group on earth at any given time during the 19 centuries since Pentecost. Accordingly, the "domestics" are these followers of Christ as individuals.
Some readers may feel that this is a rather sectarian view of matters. Or they may object to the idea that the "slave" and the "domestics" represent the same class, one as a composite body and the other as individuals. The objectors may argue that not all of Christ's anointed disciples have a share in preparing the spiritual food, so that perhaps the "slave" pictures only the leading ones, and the "domestics" those they serve in the congregation.
There is no point in trying to force an interpretation of the parable. Self-deception is of no benefit and is spiritually damaging. Therefore, we must look to the Scriptures for an understanding. In doing this, what do we find? ...

Thus we see a clear Scriptural basis for saying that all anointed followers of Christ Jesus make up God's "servant," with Jesus as its Master.
w64 6/15 p. 365 par. 23 Jehovah, the God of Progressive Revelation
The holy spirit of Jehovah is working mightily today! How thankful we should be for the provision God has made of this slave class, the modern spiritual remnant, as they faithfully dispense the revealed truths of Jehovah! With these rich truths to light the way, Christians do not grope in this dark, jungle-like world as do the masses of people in Christendom and heathendom alike. To the contrary, Jehovah's faithful witnesses have been progressively brought to an understanding of Jehovah's purposes, which are clearer now than ever before in history.
w54 9/1 p. 532 par. 14 Recognizing the Theocratic Organization for Life
14 For years it used to be thought that this "faithful and discreet slave" was one man or was the responsible office to be filled by an individual man. But is the visible theocratic organization dependent upon any single man for spiritual "food at the proper time"? No; and now in the light of accomplished prophecies we correctly see that the appointed "slave" is a class, the remnant or the remaining ones of the anointed, spiritual followers of Jesus Christ who are called to be joint heirs with him in his heavenly kingdom.
w23 3/1 p. 72, par. 48, Loyalty the Test
If, then, we believe that the Lord is present, conducting his harvest work and the setting up of his kingdom; if he chose Brother Russell as his "faithful and wise servant" and made him ruler or overseer of his goods; and if Brother Russell, acting under the Lord's supervision, organized the Watch Tower Bible & Tract Society as a vehicle or channel to carry on the proclamation of the message of his kingdom and the feeding of his sheep (thereby looking after the interests of his kingdom), then the conclusion must be that this is the Lord's way. After a careful and prayerful review of all the facts in the light of the Scriptures, can any consecrated, anointed follower of Jesus say that this is not the Lord's way?
So first, careful and prayerful examination of the Scriptures revealed that Russell was the FDS.
Then it was correctly seen that the FDS is a class and comprised of the remnant of all anointed ones on earth.
The objection was made that the FDS was only the leading ones, but clear, scriptural understanding showed that it was not the case. The facts are that the FDS is all anointed Christians on earth at any given time from 33 CE onward and this is one of the revealed truths from Jehovah.
The scriptural evidence now shows that the FDS is a small, composite group serving at WT HQ during Christ's presence from 1914.
