These little tanks (O & K works #3177 in 1908, 10844 in 1924) were among the smallest 8-coupleds to serve a German railway. The 1908 engine was named Gluckauf, the 1924 example "Trusetal".
Both used the Klien-Lindner system of articulated axles to decrease the turning radius. Perhaps the best-known examples of such engines were the prolifically produced "Brigadeloks"; see Locobase 3853.
4531 was scrapped in 1962, but 99 4532 was preserved.
