The plaid gabardine fabric goes way back in Mercedes history, even before WWII, and appeared on some examples of the 500K and 540K (brown and tan). It was a characteristic part of postwar Mercedes racing livery, such as on the SLRs (including Moss's SLRs, usually in the blue plaid), but Mercedes also offered Gullwings with green, red, and a Scottish tartan green and red, among custom choices.
