The Last Supper in Luke

Luke 22 19 to 20 contains the last supper speeches, relatively well known in which Jesus says that his body will be broken for you and his blood will be shed for you. In Luke's gospel, it's done differently. There are old manuscripts of Luke,. ancient manuscripts that omit about half of that. So he's saying that his body is given for you. The cup is the new covenant. My blood poured out for you. That verse and a half is missing from a one very old Greek manuscript and several old Latin manuscripts. And so the question is, did that originally occur in Luke or not?
