Data from Eric V Snall, "Recent Swedish Locomotives", The Locomotive Magazine, Volume VI [6] (November 1901), p. 189. Works numbers were 22-24 in 1894 and 27 in 1895.
These locomotives used the Lentz stayless boiler and corrugated firebox. According to Eric Snall, the Lentz's virtues were a lower construction cost, easier changeout of new for old firebox, good water circulation, large steam space, and therefore dry steam. It was very similar to the Vanderbilt boiler.
