Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T44. (For roster details, see Josef Pospichal's Lokstatistik at [], last accessed 15 August 2019.) Works numbers were 753-758 in 1860.
Six French six-coupleds (suggests a new version of the 12 Days of Christmas) apparently suited upper Italy railways quite well as they lasted into the 20th Century. They had a standard layout for such freight engines, although their drivers were a bit taller. The dome sat well forward, just ahead of the sandbox (which sanded the rails only ahead of the middle drivers).
