1970s German Schrank storage wall unit

My parents bought this schrank/shrunk wall unit when they lived in Germany in the early '70s. It's moved with them from Germany to two more houses. It's comprised of two long pieces and the rest can be dismantled.

There are three cabinets across the top and three along the bottom. The bottom cabinets can be locked and each have their own key still. The top cabinet doors have magnetic closures. A TV cabinet, which can be locked and has a key, is on the left side while the right side was used as storage for liquor and barware. It has a drawer beneath it which is missing one decorative knob. In the center of the unit are two more cabinets with etched glass doors.
