Does anyone recall a book that was covered I'm the book study that touched on 607 and basically said jw's were one of the only that followed the 607 date?
Are you thinking of the Proclaimers book? JWs went through it weekly in the TMS meeting quite a while back now.
They wouldn't have said they were 'one of the only' to follow the 607 date (or rather, the 606 date back then) as the fall of Jerusalem because it was only really Barbour and Russell who believed that. Others did count periods of prophetic time from 607/606, but they understood those years to be the beginning of Nebuchadnezzar's reign rather than his 18th year when he destroyed Jerusalem, thereby more in keeping with conventional chronology.
Ah, here:

Noteworthy too is what Brother Russell did with other highly significant truths that he learned from God's Word. He discerned that Christ would return as a glorious spirit person, invisible to human eyes. As early as 1876, he recognized that the year 1914 would mark the end of the Gentile Times. (Luke 21:24, KJ) Other Bible scholars had likewise perceived some of these things and had advocated them. But Brother Russell used all his resources to give them international publicity on a scale then unequaled by any other individual or group.
Also see p. 134-5 (bear in mind that the statements about John A. Brown are partially incorrect - he never connected Dan. 4's '7 times' with the 'Gentile times' of Luke 21:24).
Oh and
