The Du Croo & Brauns mallets turned out were basically of the same type, varying only in small appliances on customer's demand. Basic dimensions were all the same. They were produced in two power categories, 60 hp, all engines produced in 1926 and 80 hp, all later engines, with one exception as there was a one off 100 hp example (builder's no 203). All mallets were built to 700mm gauge.
Two examples were built with an auxiliary tender, nos 177 and 191. All Mallets were shipped to Indonesia. The engines had, and maybe I may write "have", an extreme longevity as the accompying photos testify, being taken as recent as 1997. Sightings have been reported well past 2000. Some engines even look well cared for, despite the harsh working condition sugar mills usually present.
