Well, this is half the "problem" isn't it? A total lack of consistancy;

Racer38's SP looks quite good though the plastic is a bit brittle.
Billy's old 21sp was (we think) the same sort of bodywork, it had those same squares to connect the front panels that you see on all the ones on ebay. That was really good, the fact it was 28 panels on a 21 meant that the "wrong" paint job (a 21SP job on 28 bodywork) didn't matter and it was good plastic.

Whatever you like, to me a Rothmans 28SP is an mc28 with white Magteks, blue topped forks, se/sp discs, a dry clutch motor, o.e. Rothmans panels and looks like this.
