If you go to the technical manual tab, there is a listing for paint and color codes. Click on that link and then go to the upholstery codes. You can then scroll through the various colors, 114 is listed. Below the MB Tex codes are the ones for leather. It appears from the pictures that 210 leather (natural 1068) is a decent match. No substitute for getting a sample from a potential supplier as the colors on the computer screen are not always what you see with the actual leather.
Good luck and welcome to the forum!
