Apparently held in 'a library within a library' the scroll is classified as BFBS MS 231 and is very damaged in parts with mold and tears in certain sections and as a result has split into two parts in its wooden box. the conservators would only allow one half to be looked at, though actually the damaged area only went through a couple of yeriot (sheets) depth.
Below: a selection of photos showing the scroll unrolled, areas with particular damage and some of the special letters derived from Sefer Tagin. A particularly spectacular example of correcting by writing between the lines (how they used fix - I did similar with the Tyburn Megillah). Also Dr Gordon examining particular areas, the interesting Ha-azinu poem layout and me holding the final yeriah open (yes that is my arm!)
