It is hard to tell unless there is a picture of the top part. If the chrome is all straight with no cutout curve, then they are for the 250 early 280SL's.
If there is a cutout curve, then it belongs to a coupe/convertible 220SEb, 250SE, 280SE or 300SE.
If looking to sell, then put it in the "For Sale" section on the website.
