While I can't furnish the information you need, I hope that you'll share the requested information here when you get it.

A call to the Mercedes Benz Classic Center parts center in Irvine might help -

As some of the w126ers now are 25+ years old now, and no longer subject to gray market restrictions, maybe the parts you need are available right from them. Tell them your w126 is a 1982 or any model year up to a 1988, ie, a 25 year or older car when you call.

Get also, the proper grain-of-wheat bulb for the headlight switch on the dashboard, on the w126 euro cars - so when you turn on the fogs, the ornge dot on the middle of the headlight switch will illuminate as a reminder the fogs are turned on.
