On the following day I came to the packing into the workshop and what a surprise: The building group waited already full longing for me that I would issue it into a pendulum packing to put and the delivery note for Augsburg. This was the last contact with this plate, since she would be distributed now from Augsburg directly to the competent authorities in Berlin. Thus I experienced nearly the whole run, which such a building group goes through with Siemens.

The reference to pendulum is perhaps for indicating that the packing material shuttles between the consignee and the dispatcher. Hope my suggestion helps the asker
