History

The Saxon III was built in 1871 and 1872 by the Hartmann (66 examples) and the Maschinenfabrik Esslingen (21 examples). Fourteen of the Esslingen engines were subsequently given a Nowotny-Klien bogie instead of the original fixed leading wheels and were then reclassified as the IIIb.

The Reichsbahn only took over one of the unmodified engines - no. 274 BRÜNN and number her as locomotive 34 7611.
