No, it's what Simonides clearly said - and he was so clear about it, he even referred to the book covers and their having been replaced at the book binders. He would have known the Codex Alexandrinus was bound. He says NOTHING about rebinding the quires.
Bradshaw wins. You lose. What penalty will divine justice impose on you, for you being wrong?
".....very bulky volume, antiquely bound, and almost entirely blank parchment"
"I therefore took possession of this book, and prepared it by taking out
the leaf containing the discourse, and by removing several others injured by
time and moths, after which I began my task. First, I copied out the Old
and New Testaments, then the Epistle of Barnabas, the first part of the
pastoral writings of Hermas in capital letters (or uncial characters) in the
style known in calligraphy as άμφιδέξιος (amphidexios). The trancription of
the remaining Apostolic writings, however, I declined, because the supply
of parchment ran short, and the severe loss which I sustained in the death
of Benedict induced me to hand the work over at once to the bookbinders of
the monastery, for the purpose of replacing the original covers, made of
wood and covered with leather, which I had removed for convenience - and
when he had done so, I took it into my possession."
