Here’s a beautiful original Roser leather Darker red cabriolet boot cover for the W180 220S/SE.
The leather is in fantastic condition and you will not be able to replicate the color with something new to match your interior. I show the color next to #243 Red of a 190SL cover I have.

The chrome on the original Knopf snaps ( says, Der original Knopf ) are in excellent condition and spring.
The interior red felt is also in good condition.
