Data from "The Works of Messrs Henschel & Sohn, Cassel", The Locomotive Magazine, Vol VI (September 1901), p. 152.
This was the very first Henschel locomotive (i.e., works number 1) and it left the factory in July 1848. It had the familiar four-sided firebox and long boiler of the time, closely spaced leading truck axles, regulator (throttle) placed well forward by the stack, and inside motion lnked to outside cylinders using rocker arms.
