Data from "New Locomotives, Leopoldina Ry", The Locomotive Magazine, Volume XV [15] (14 April 1909), p. 68. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers were 3347-3349 in 1909.
This set of small Eight-Wheelers had Belpaire fireboxes. In the profile all the verticals stood resolutely upright.
