As you can see, many of the aftermarket suppliers have levers with colors which are not quite right on three of them (reds and blue) and is completely wrong on the fourth which should be smoke or grey (not orange). I just installed a set from Mercedes and the colors are correct and noticeably different from many after-markets. Of coarse the parts cost is higher from the dealer.
Also if you have a W113 with center speaker, you will have to slightly modify the grey lever wherever you get it. Compare it closely to the original.
