Try looking on eBay Motors for a manual - I found a lot of things I needed on there. Start within the "Manuals and Literature" section, and you can search for Mercedes, 230E, W123, and so on.
Just a guess, but since there seem to be 4 identical buttons, could those be for your windows? On mine, those are all centered around the shifter.
Good luck, and welcome to the forum!
