Data from [] (last accessed 2 March 2007) and from Christian Lindecke [] (visited 28 November 2003) -- translated by Google.
The first eight engines had a Kessler-patent boiler with a dome; these were delivered in 1846 by Kessler (4) and Maffei (4). All of them had been retired by the end of the 1860s, doubtless because of their small size and power had long since been overmatched.
According to Lindecke, the Pfalzbahn ordered 2 more in 1851. Unfortunately, one of them fell into the Rhine during its delivery trip. The surviving engine -- dubbed King Ludwig -- later received a boiler without a dome and its stack and cab were later modified as well. The little engine was retired in 1883.
