Data from Sebastian's Homepage [] (visited 17 Nov 2004). These tanks were procured for the Steyertalbahn in 3 sets. The first 3 (works #1993-1995) arrived in 1888 and were named Steyr, Sierning, and Grunburg, respectively). Molln (works 2256) came next in 1891 and Letten (works 2501) followed in 1891. After a long break, Klaus (works 6925) completed the sextet in 1914.
Steyr was scrapped in 1937 and hence never had a German Railways class number. Two others -- Grunburg and Letten -- stayed with Steyr until they were scrapped in 1963 and 1965, respectively. Sierning went to the OEGEG as did Klaus, while Molln later operated on the OeG Localbahn.
Six more similar tanks built by Krauss in Munich went to the Caltalunyan San Feliu de Quixols - Girona as that railroad's 1-6 (works 2355-2358, 2826 all in 1891, and 5267 in 1905) Two others went to tram railway Tram Onda - Puerto Castellón (works 2392-2393 in 1891) and much later wound up with the SFG.
Sebastian says the major differences were the gauge (75 cm instead of 76 cm) and a shorter stack. Several have been preserved and photos show low-riding cylinders under a tapered stack, tall steam dome over the leading axle (mostly cylindrical, but at least one in the class now shows a tapered dome), small, square regulator box, long side tanks, and oversized cab.
