R129 1999 original wheels

Anyone know if these wheels were optional fitment for a 1999 r129 or are they later/aftermarket wheels? They are 18s which seems unusual on a 320SL.

Thanks guys. I thought they didn't look right and even the centre cap looks wrong. Cheers

Thanks for the info. Ouch at the price of some of the wheels!
