Yesterday, the blog which was setup to detail the preparations has made an update which shows the new vestments that were commissioned, the crozier that will be used and some of the sanctuary setup generally.
("...this will be passed from Cardinal Cormac Murphy-O'Connor to Archbishop Vincent Nichols during the Mass of Installation. It forms part of Westminster Cathedral's Cardinal Howard Plate - an Italian silver-gilt service of ecclesiastical plate, formerly the property of Cardinal Edward Howard and presented for the then future Cathedral of Westminster on 10 November 1893.")
