Data from diagram Loco: 156, Societe Alsacienne de Construction Mecaniques from SACM locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). SACM-Grafenstaden works numbers were 6749-6760 in 1914 and 6814-6828 in 1915
Compared to Schwarzkopff's long-running production of over 1,000 T16s for the Prussian State Railways, SACM's contribution served only the EL (French Alsace-Lorraine before 1871 and after 1918--except for a 1940-1945 interlude again under German occupation). The first twelve took shape in as the original T16 design. Six more arrived in 1915 as part of a fifteen-locomotive order for Prussia; these T16.1s rode on a reinforced frame that carried more water and coal and included reinforced brakes.
Locobase 15547 describes the Schwarzkopff variant and Locobase 5736 describes the even -more-numerous T16.1.
