Simon, the remote exhausttemperature readings was a novelty and technically fairly advanced. In those days exhausttemps had mostly to be recorded locally at each cylinder outlet. As to the engineroomtelegraph, the dial is different from a conventional type, on the ahead side was dead slow (Kleine fahrt), slow ( Langsame fahrt), half ( Halbe fahrt), full (Grosse fahrt) and outmost power ( Ausserte kraft) the last did overload the engine ( we used it, unofficially, sometimes homeward bound after 3 weeks at sea.) On the astern side was an additional order as well: "diving" (Tauchen).
