Data from Baldwin Locomotive Works Specification for Engines, 1903, as digitized by the DeGolyer Library of Southern Methodist University Vol 28, p. 218. Lionel Wiener, "Locomotives of the Rio Grande do Sul", Volume 19 (15 May 1906), p. 106. Works numbers were 27450-27454 in February 1906; 29194-29195, 29232-29233 in October.
The Cie Auxiliaire de C de F du Bresil paid for nine small Moguls that were delivered to this road in 1906-1907. Wiener commented a few years later that these were the last American-built locomotives supplied to the CA.

Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Volume 19 (14 June 1913), p. 150-151. See also R Weatherburn, "Brazilian Railways and Locomotives", Railway Times, Volume 92 (31 August 1907), pp. 221-222. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers were 6264-6266 in March 1907, 6539-6542 in November, 6543-6545 in December, 6589-6592 in July 1909, 6593-6594 in August, and 6595-6598 in October.
See Locobase 20225 for a description of the 67-locomotive order contracted with Borsig in 1906. This entry offers data describing the Moguls. Weatherburn's comments on the design focused on an engine "combining the peculiar features of both hemispheres" The result was an engine and tender that freely adapted "to a road which has become twisted or distorted by the heat" in a way that was "very satisfactory." The short-coupled driver set with the drive on the rear axle and a flangeless middle axle contributed to system in which the "engine, with its most elastically constructed tender bogie" adapted itself to "any practicable curve."
Weatherburn described the valve gear as a combination of Joy and Walschaert. A copper firebox burned either wood or low-calorie coal briquettes.
Another example of the design's mixed influences was the reversing gear. With a the turn of a small handle, the driver could operate it as a European-style screw reverser or the North American lever.
