The locomotive was produced by Officine Mechaniche Napoli (Italy) in 1914, serial nr. 563. In total, 470 locomotives of this series were produced and are believed to be one of the best Italian made machines. Between both world wars (when western Slovenia was a part of Italy) these locomotives were in use on sections between Trieste, Postojna and Rijeka and in Istria. After the WW2 one of the locomotives (not this one) was incorporated into the Yugoslav Railways' rolling stock and assigned the number JŽ 25-035. This locomotive was acquired (exchange) from Italy in 1982 and exhibited at the Postojna train station. It was assigned the invalid Yugoslav number JŽ 740.121 which can still be seen on its left side.
