Ol12-7 (429.195) was originally delivered to the kkStB but between the two world wars and became PKP-A: No. Ol12-43. In 1939 it was seconded into the Commissariat of Railways (NKPS), i.e. Soviet Railways but, from 1942 - 1945 became DRB No. 35 817, as it did with ÖBB 1945 - 1947. For a very short time in April 1947 it again worked for the Soviets, by then renamed Ministry of Railways.Note: SŽD did not come about until 1954! It was displayed in 1973 at the Warszwa Open Air railway museum and had reconstruction work at ZNTK Pila in 1993 and later went operating from Skansen Chabówka but its boiler ticket expired in 1999. It was returned to service in 2008 after major repairs and remains based at the Skansen Taboru Kolejowego, 34-720 Chabówka, Lesser Poland.
