Data"Oesterreischen Lokomotiven fur Griechenland", Die Lokomotive, Volume 24, No 1 (January 1927) pp 1-6. Works numbers were 2020-2029 in 1888, 2107-2109 in 1889, 2253 1892.
The Austrian Southern class described in Locobase 11256 also came from StEG's Vienna works and offered very similar weights and dimensions. But the class served the Chemins de fer Orientaux in what was then Ottoman-controlled Greece from Salonika on the Aegean Sea to the Balkan possessions at Skopje in Macedonia and Vranje and Nis in Serbia.
