What do you know about this wheel?

So here is my first newbie post...
Several years ago when I bought my 91 500SL it did not have the original stock wheels on the car. They are clearly a few years newer and chrome. The owner (a friend) I bought it from had it for 10 years and those were the wheels on it when he purchased it. Eventually I decided to source OEM and return the car to its original state. I now have these wheels on the car and spare and have no need for the chrome set.
I have done research on wheels but have not been able to reach any conclusion other than they are aftermarket and were not originally chromed. I plan to sell them and want to know what they are so that the description is transparent and honest.
So, does anyone know what these are?
