Brother George is correct on this, pretty common knowledge among KJV circles of reference...

"Linguistic scholars have observed that Codex Vaticanus is reminiscent of classical and Platonic Greek, not Koine Greek of the New Testament (see Adolf Deissman's Light of the Ancient East). Nestle admitted that he had to change his Greek text (when using Vaticanus and Sinaiticus) to make it "appear" like Koine Greek."

"Codex Vaticanus contains the false Roman Catholic apocryphal books such as Judith, Tobias, and Baruch, while it omits the pastoral epistles (I Timothy through Titus), the Book of Revelation, and it cuts off the Book of Hebrews at Hebrews 9:14 (a very convenient stopping point for the Catholic Church, since God forbids their priesthood in Hebrews 10 and exposes the mass as totally useless as well!)"

That last part is not relevant but I had to leave it in just for fun...

"Linguistic scholars have observed that the Vaticanus is classical and Platonic Greek, not the Koine Greek of the New Testament. Codicologists note that the Vaticanus was written on vellum scrolls (skin obtained from animals not yet born), and not papyrus codices, as were used among "the early Christians." The Vaticanus omits crucial parts of Mark and Luke. Theologians question its lack of use by anyone for 1300 years, then its "sudden" discovery in the Vatican in 1481. Protestant researches have never been permitted to examine the actual manuscript and work only from copies provided by the Vatican."
