Right on Finkelstein ... It still gets me that I have not found this Watchtower quote anywhere online, including jwfacts.com or this website until very recently and it is on JW.org. Maybe I missed it in my search. I don't know but this is the quote again almost 3 years old now, like I said, maybe I missed something:
"Finally, we examined why Jesus’ arrival to appoint the faithful slave over all his belongings did not occur in 1919 but will take place during the great tribulation. So, then, all three “whens” apply to the same future time period—the great tribulation. How does this adjusted view further affect our understanding of the illustration of the faithful slave?" Watchtower Study Edition July 2013
Edit: Ok, I did find it on this site quoted a year ago just now: https://www.jehovahs-witness.com/topic/378430001/1995-generation-change?page=6&size=10
