Remember, Jukka, Henschel Flugzeug-Werke was located at Berlin-Johannisthal. After the end of the war, the Red Army took over the property, dismantled the factory - back then one of the most modern aircraft production plants in Europe - and took it back to the USSR. Most documentation is probably lying somewhere in a Russian archive, way beyond my possibilities - if it still exists, of course.
