genuine OEM Mercedes leather seat cover for the back of a W109 front seat.  The cover is a cognac brown color and in overall excellent condition.  It has been stored in a climate controlled facility for decades.  The part number is 109-910-39-47 and the piece is new old stock.  Note in the pictures that some of the stuffing and material in the back seat is missing.  We have most of the stuffing but it is worth pointing out that some of the liner needs minor repair.
