(Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers were 23592, 23597 in 1937

Henschel delivered the first two of these powerful non-articulateds in 1937. After World War II, Skoda repeated the design in its production of nine more locomotives (works numbers were 1977-1978, 1980-1985, 1990 in 1949.
