I have a copy of Franz's University transcript on my computer I lifted off some website.
Franz's formal training was mainly in classical Latin and Greek. He only coompleted one half of a course in Biblical Greek which ran a year long durning his last semester there. Since Koine is pretty close to Attic Greek, save the Aramisms, It doesn't mean he was incompetent at all, though it is generally accepted that one should have an advanced degree to go into that work, which Franz didn't.
My problem is the same one which the first link had with Franz's work. In 1950, the Watchtower said the follwing with respect to the NWT:
*** w50 9/15 p. 315 New World Translation of the Christian Greek Scriptures ***
9 We acknowledge our debt to all the Bible versions which we have used in attaining to what truth of God’s Word we enjoy today. We do not discourage the use of any of these Bible versions, but shall ourselves go on making suitable use of them. However, during all our years of using these versions down to the latest of them, we have found them defective. In one or another vital respect they are inconsistent or unsatisfactory, infected with religious traditions or worldly philosophy and hence not in harmony with the sacred truths which Jehovah God has restored to his devoted people who call upon his name and seek to serve him with one accord. Especially has this been true in the case of the Christian Greek Scriptures, which throw light and place proper interpretation upon the ancient Hebrew Scriptures. More and more the need has been felt for a translation in modern speech, in harmony with revealed truth,...

Knowing that, from Genesis to Revelation, the stated overiding principle of translation for the NWT was to produce a translation in harmony with Watchtower theology makes the NWT a translation one cannot trust, even if Franz had held a Ph.D. in biblical languages. Maybe if he had he'd done a smoother job with some of the more problematic renderings in the NT, but that doesn't mean that one would want to trust it, no matter how good parts of it might be.
