A post on the Facebook Mercedes Pagoda W113 Club Group page today is searching for the owner of a 1968 280SL, ID # 113 04410 003822.
It was a gray market import from Germany to California in the late 70’s/ early 80’s. The poster has a folder of paperwork for the car you can have for free.
He apparently also has the paperwork for a ‘63 230SL.
Here is the poster, David Michael:
