Sotheby's currently have an online sale including more than thirty single leaves from Otto Ege manuscripts, including a leaf from his well-known 12th-century Italian Gospel Lectionary, shown above. I helped to catalogue the sale, giving me a reason to reconsider the parent manuscript, which I have not really thought about since a blogpost in 2016.
The main purpose of my 2016 post was to share a 1937 description of the manuscript before it was was disbound and dispersed, but I did not pursue this to its logical conclusion, to see how much we could deduce about its provenance and contents from the old description and available images.
The 1937 description provides some liturgical clues:
"... amongst the Saints [in the Sanctorale are:] S. Sabinus (Jan. 17th), S. Gregory martyr (Feb. 4th), two feasts for St. Benedict (March 21st and July 11th), S. Antoninus mart, S. Archelaeus, St. Zenon etc. etc. ..."

It is perhaps also worth mentioning that leaves at Cincinnati Public Library, Greensboro, and Chapel Hill have cantillation markings, "p", "c", and "s" in red:
Such cantillation notes are not fully understood, but are thought to represent the person/people whose words/viewpoint are conveyed by the text of the Passion narrative (mainly a 'narrator', Christ, and the Jews or other participants), and/or the rank of the person who would read these different 'parts' as if in a play (e.g. the priest, cantor, and subdeacon), and/or the pitch/tone at which the words were said/chanted (e.g. tacite, clare, and sonoriter). For comparison, and to show how different manuscripts used different letters of the alphabet, here is an example from a 12th-century Gospel Lectionary probably from southern Germany, with the superscript red letters "t", "c", and "a":
