O&K 0-8-0 Klien-Lindner narrow gauge locomotive No 22 on a French post card with handwritten note "Roblès Meu". Probably one of a batch of O&K locos built for contractors Léon Chagnaud & Fils for the Bou Hanifia dam in Algeria. O&K built 20 of these locos, 750mm gauge, in 1930–32 for the Bou Hanifia dam construction, of which seven or more ended up with Brazilian sugar mills (probably in payment of French war debts to Brazil). Frei Caneca had two, O&K 12259 and 12337, both of which survived. No. 6 is at Usina Alta Paulista in Junqueiropolis SP, No. 5 is at an engineering firm in Catende PE. No. 32 from the dam construction looks identical.
