Data from UG Type 175, Societe Alsacienne de Construction Mecanique of SACM Locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). Works numbers were 1951-1954, 1650-1652, and 7653-7655.
The first of these engines were among the first Mallets to be built. The source shows 22 having been built from 1892 to 1932.
