This is one (1) leather cover seat set for a W123 model which includes one (1) back cover and (1) bottom cover.  There are a total of two (2) covers in the set.  These are genuine OEM Mercedes leather seat covers in a palomino color.  The part numbers are 123-920-42-46 and 123-920-48-49.  Note these covers have been dry stored in a climate controlled facility for decades and are new old stock.  Note on part number 123-920-42-46 there is some stuffing that is missing in the back of the seat cover.  It may be due to the fact that the original plastic packaging is not available.  Good news, we have the stuffing that came loose and will include it with the sale.
