First you said that scholars couldn't even see the originals. That having been disproven, now you demand proof that they can "handle" the originals. Next you'll want proof that Martin Luther was raised from the dead and permitted to eat at least one page from Romans or Galatians.
You know very well that if they let people handle those manuscripts on a regular basis that they would be dust after 50 years.
And how in the world does anyone judge if a manuscript is an "original" if it cannot be taken out of the shadows of a small room in the basement of the Vatican?
That having been disproven...
Nothing has been disproven, except perhaps the integrity of the Vaticanus.
