In France during 1940 german with french collaboration governement at vichy (Laval Petain) took many of qualified workers they call that STO
"service travail obligatoire" and send them in Ruhr working on tools machine shop to produce armaments krupp henkel siemens messerschmitt dornier etc... I 'm not here to talk about politics that's not the goal of this forum, but only history comparing to this complex model and try to explain facts
here's some poster of this time
the one with the two men say
"For defense what kind of weapon you will choose the gangster's automatic gun or a worker's tool"
The yellow poster: " I work for germany for the future for my family for france, do it like me"
In fact due to pressure from occupants Laval exchange workers to POW
and with the needs in Germany with Speer to produce more and more, many didn't come back
Anyway my building is after war and produce locomotives, it's fictive impossible to realize all the complex.
The machinery on top is for the next big hall the erecting shop
