Craig, I'm sure that is what the WTS says now about Jesus ruling since 33 CE.
But the 1874 is more tricky because it was that Jesus was king already but had not begun ruling completely until 1914. It is very similar to the concept that Jesus began ruling as king in 1914 but is ruling in the midst of his enemies until Armageddon when he destroys his enemies on earth completely and abysses Satan and the demons for a 1,000 years.
The then-Bible-Students, ergo Russell, taught that only the governments, financial and religious systems were to be destroyed in 1914 and that the remnant would be taken to heaven to rule with Jesus for a 1,000 years over all humans alive then on earth and the ones to be resurrected (some 50 billion per Russell).
For that I will have to do a little searching in the older books of Russell unless someone already knows what I am talking about and has a quote from the Studies in the Scriptures.

A quote for Craig
*** w94 6/1 29 "Jesus Christ Is Lord"-How and When? ***
And Jesus Christ has ruled as King of kings and Lord of lords over his congregation since Pentecost 33 C.E. But now, since 1914, he has been given kingly authority to rule in that capacity with his enemies placed as a stool for his feet. The time was now ripe for him to go subduing in the midst of them, all in fulfillment of Psalm 110:1, 2.Hebrews 2:5-8; Revelation 17:14; 19:16.
Quotes from the WTS that is interesting about the year 1874
*** w55 1/1 8 Part 1: Early Voices (1870-1878) ***
"Hence, it was in B.C. 606, that Gods kingdom ended, the diadem was removed, and all the earth given up to the Gentiles. 2520 years from B.C. 606 will end in A.D. 1914, or forty years from 1874; and this forty years upon which we have now entered is to be such a time of trouble as never was since there was a nation. And during this forty years (1874 to 1914), the kingdom of God is to be set up (but not in the flesh, the natural first and afterwards the spiritual), the Jews are to be restored, the Gentile kingdoms broken in pieces like a potters vessel, and the kingdoms of this world become the kingdoms of our Lord and his Christ, and the judgment age introduced."Three Worlds or Plan of Redemption, pp. 83, 189.
*** w55 3/15 173 Part 6: 1914 Date Verified ***
In view of this strong Bible evidence, Rev. Russell wrote in 1889, we consider it an established truth that the final end of the kingdoms of this world and the full establishment of the Kingdom of God will be accomplished by the end of A.D. 1914.

Something else that was seen as a possible time indicator involved the arrangement that God instituted in ancient Israel for a Jubilee, a year of release, every 50th year. This came after a series of seven 7-year periods, each of which ended with a sabbath year. During the Jubilee year, Hebrew slaves were freed and hereditary land possessions that had been sold were restored. (Lev. 25:8-10) Calculations based on this cycle of years led to the conclusion that perhaps a greater Jubilee for all the earth had begun in the autumn of 1874, that evidently the Lord had returned in that year and was invisibly present (not 1914), and that "the times of restitution of all things" had arrived.Acts 3:19-21, KJ.Based on the premise that events of the first century might find parallels in related events later, they also concluded that if Jesus baptism and anointing in the autumn of 29 C.E. paralleled the beginning of an invisible presence in 1874, then his riding into Jerusalem as King in the spring of 33 C.E. would point to the spring of 1878 as the time when he would assume his power as heavenly King. They also thought they would be given their heavenly reward at that time. When that did not occur, they concluded that since Jesus anointed followers were to share with him in the Kingdom, the resurrection to spirit life of those already sleeping in death began then. It was also reasoned that the end of Gods special favor to natural Israel down to 36 C.E. might point to 1881 as the time when the special opportunity to become part of spiritual Israel would close.
That 1878 was a year of significance seemed to be fortified by reference to Jeremiah 16:18 (Jacobs double, KJ) along with calculations indicating that 1,845 years had apparently elapsed from Jacobs death down till 33 C.E., when natural Israel was cast off, and that the double, or duplicate, of this would extend from 33 C.E. down to 1878.
