Got a Carlton super corsa - the original version. Rleigh bought up Carlton in 81 and took over the corsa marque.
Super corsa was same frame as the tream bike but notch down components.
Unfortunately it is a 21 1/2. stick a long stem and layback seatpost on and it will fit fine..
PM me if interested and I'll send picks, component list and price!
Cheers
Sam
