Thanks for the correction of both hands...but unfortunately,
"The rifle was sent to the FBI laboratory, where Sebastian Latona found that “there was nothing visible in the way of any latent prints on there” (Warren Commission Hearings, vol.4, p.3). Latona applied silver nitrate to the bag, and discovered two partial prints that were matched to records of Oswald’s prints (ibid., p.6):
a part of a right palm print (Warren Commission Hearings, vol.17, p.286 [Commission Exhibit 632]);
and a part of a left index fingerprint (ibid., p.287 [Commission Exhibit 633]).
Although the bag, or at least the paper that was used to make the bag, appears to have come into contact with Oswald’s hands at some point, the fingerprint and palm print evidence was insufficient to prove that Oswald had carried the bag in the manner described by Randle and Frazier, or that he had assembled the bag by hand."

The bag is being held in the fashion described by Linnie Mae. The right hand grasping the barrel of the rifle. The person who wrote the article seems to think the bag was being held vertical with one hand alone. That is not what she describes and who would carry anything in that manner. The Warren Commission could have done a better job of getting her to describe how it was exactly being held. Buell having it cupped in his hand and jammed into his armpit, no matter what anyone could be carrying does not even remotely seem plausible.
Linnie Mae even gets the length right with 3 feet 6 inches.
It is like Buell is talking about a whole other bag or simply “I never paid attention” is correct.
Mr. LATONA. The palm lay in this fashion here.
Mr. EISENBERG. You are putting your right hand on the paper so that the fingers are pointing in the same direction as the arrow A?
Mr. LATONA. That's right.
Mr. EISENBERG. And it is at approximately right angles to the paper bag?
Mr. LATONA. That's right.
