Not quite sure what you mean by Apocrypha. Do you mean the books of the Septuagint that are not accepted in the canon by traditional Jews and Protestants, but are by Roman Catholics and Eastern Orthodox churches?
I remember a WT QFR back in the 50s or 60s that asked whether Jehovah had a hand in restoring the temple during the Maccabean revolt in the 160s BC (recorded in 1 and 2 Maccabees). Freddie Franz wrote the reply, clear from his strange writing style. What he said was that the temple had to be standing in order for the prophecies about Jesus to be fulfilled. I don't recall him citing or quoting any specific passages from 1 or 2 Macc., but it may be the closest the WT publications have come to utilizing the Apocrypha in any sort of "positive" way. I also remember reading in the WT publications, much later than the above QFR, some author putting down some of the elements in the book of Tobit as superstition. The context was a general condemnation of the Apocrypha as a whole.
You seem to think that there are some passages in the Apocrypha that the GB could use "to keep up the Organization and the $ flowing in." What part of the Apocrypha do you have in mind that would help them do this???
