Comparables.  Two similar German cupboards were sold at Sotheby's "Property from the Royal House of Hanover" sale on 10/5/2005.  Lot #1402 has a near identical style to the frame, and lot 1401 shows a little different style.  These lots can be seen at the following links:

Condition:  The exterior is in excellent condition, but the back of the upper section was removed, and another board cut in modern times (probably to fit a large TV for an entertainment center).  The back will need to be replaced.
