Antique Desk or Table Push button Buzzer Silver Argento Wien Man with Roller For Sale

Up for sale is a hotel desk, CEO office, or perhaps a dining room table in Europe pre WW2, electric buzzer used to summon unseen servants. The figure is of a man in office attire, I assume, toiling at the most backbreaking type of work, pushing a heavy compactor. There are a lot of messages here. The buzzer holder is silver plated and is marked Argento Wien. See pics for size and detail. Truly a stunning piece!
