Looks like my memory wasn't quite there. I found my old frame via Google images and linked back to the buyers bike thread on here.
It seems my forks were triple cour, not plain yellow. I can't recall if I bought the frame and fork with the mc1 or if I sourced that separately, but mine was black not yellow.

Like you, I wanted to tick the Klein box. I did the yo of sorts, again bought it too small but I can at least say I owned one.
