I've been tracking the location of a number of fragments of the scrolls in various collections, including those in the Green Collection. The one exhibited at OKC Museum of Art is a fragment of Gen.32:3-7 that previously was the property of the book dealer Michael Sharpe. There is a nice photograph on the Passages website, go to the newsroom and then within that to Green Collection Photo Gallery. See here.The photo of the scroll fragment is the third one down on the far left.
Background on the exhibition is here.
