From The Italian Railways Society research & an Italian website, the World War Two Railway Study Group has identified an SR 12t Ferry Van in a photo taken in Vibo Valentia.
Apparently the van, which had Italian State Railways Engineering Department markings, was made by the SR for the WD in 1942 and was kitted out as a mobile repair shop.
Obviously wanted to retire to a place with a lot more sun than Eastbourne or Bournemouth!
