Spindle markings are 5SS F11 B, one underneath the other. There are no real bike coops here (Rome) but there are a couple of friendly LBS.
BB width seems to be 71 mm rather than 68, as close as I can measure it. The serial number on the bike is W I 9 0 0 0 2 3 7 which indeed indicates the Worksop factory.
So according to the Sheldon Brown site, and much else, it might actually be easier to replace bearings and continue to use this spindle and cups. The Velo bracket mentioned by Sheldon Brown seems to be no longer available.
