For your consideration is one of two current listings I have for Danish Modern Modular Wall Units.  Made by WK Mobel, not sure if this was designed by George Satink or not.  This listing is for the single unit, the section that has a drop front secretary desk with drawers inside.  The prior owner actually used this section as a bar.  As you can see from the pictures this piece is in very good overall condition - a few normal signs of use as you may expect.  The piece does come with the original key which works correctly to lock.  The top and features adjustable shelves, the base has felt lined drawers.  Measures 34" wide by 18" deep at the base, 13.5" deep at the top, 82.5" tall.  Note this section was attached to the other set of four, there are connection holes on the base on the left side, see pics.  Easy to install a filler if needed.
