These were the two Ten-wheelers from the original set of ten delivered in 1911 with saturated boilers (Locobase 3375).

], last accessed 1 June 2014., p. 93. Hanomag works numbers were Hanomag 3654-3668 in 1901. Henschel's fifteen arrived in 1903. (Comas's guide does not have the works numbers.)
German-built four-cylinder compounds that, like the Norte's simple Ten-wheelers, arrived on MZA rails in the first decade of the 20th Century and, in many cases, saw the end of steam many years later. They featured Belpaire boilers, outside HP cylinders, large steam dome over the rear bogie axle, smaller sand dome between the steam dome and the firebox, and a lipped stack.
They were originally delivered with three-axle tenders that were later replaced by tenders riding on two bogie trucks.
A total of 105 was built. This first group of 30 were produced by Maffei and Henschel; see Locobase 3375 for the later group.
Data from [] . Henschel works numbers were 6997-7021 in 1905, 8338-8347 in 1907, 8929-8938 in 1908, 10075-10084 in 1910. Maffei works numbers were 3250-3259 in 1911. Hanomag's works numbers, also in 1911, were 5933-5942.
Repeats of the successful 1901 compound (see 230-4001) , these engines likewise came from German builders. Henschel and Maffei added to the numbers they'd supplied earlier and they were joined by Hanomag for this later group. Deliveries came in 1907 and 1910-1911.
Two of the very last batch--871 and 874--are described as "equipped with superheated boiler"; their data are in Locobase 3359.
