This list informed me of the existence of the 'Wife-Beater's Bible' in these words:
5) It would require significantly different printings of the Matthews Bible in 1537.
Based on the Metzger reference in Ryan's comment I'm now convinced that some such thing existed, though it is rather different from what is found in the various sources I noted above. The spelling above is not original. The reference to a 'footnote' is an anachronism. It did not occur in a 1537 Bible and is not a Matthews Bible, but what it is is less clear. Metzger says it's closer to Tyndale than Taverner and his mention of Coverdale doesn't make it clear that Coverdale was actually a textual source. So it's not a hoax as I first thought, but just a very corrupt version of a historical core.
Next question: where can I see a copy?
Here is what Metzger has to say:
"Edmund Becke’s Bibles (1549; 1551)In the short reign of Edward VI, the open Bible came once again into favor, and some fourteen Bibles and thirty-five New Testaments were printed. These were reprints of Tyndale,Matthew, and Taverner, some of them of interest only for the light they throw on the liberties that publishers felt free to take with books and parts of books in producing a “hybrid” edition. One such printer/publisher was Edmund Becke, who also tried his hand at some desultory revising. Occasionally called “Bishop Becke’s Bibles,” these comprise essentially Taverner’s Old Testament and Tyndale’s New Testament, compiled by John Daye and revised and edited by Becke.
The edition of 1549 is printed in a rather peculiar black-letter type in double columns. The majority of the notes are gathered together after the chapter to which they pertain. Present also are Tyndale’s prologues, including the long prologues to Jonah and Romans (eleven pages)and that to the New Testament.
The edition of 1551 includes 3 Maccabees in the Apocrypha. A cut of the Evangelist appears before each Gospel, and at the beginning of the dedication stands a woodcut initial,representing Becke offering his book to the young king, Edward VI, and instructing him in the duties of his high station.
Becke’s alterations in this edition of the New Testament are deplorable. By reverting in nearly every instance to Tyndale’s version, he has done injustice to Taverner by perpetuating mistakes that the latter had corrected.
Both editions contain the notorious “wife-beater” note on 1 Peter 3:7, where men are exhorted to live with their wives “according to knowledge.” Becke explains this to mean
that taketh her as a necessary helper, and not as a bond servaunt or bonde slave. And if she be not obedient and healpeful unto hym: endeavoureth to beate the feare of God into her heade, that therby she maye be compelled to learne her dutye and do it. But chiefely he must beware that he halte not inanye parte of hys dutye to her warde. For hys evyll example shall destroye more than all entruccion she can give shall edifye."
