Just about! Lol
The 68 is an upgrade on the 67, with a new power unit and made from lighter materials (the 67 has a bit of a weight issue, restricting it from lots of lines)
The strange one will always be the 70, as on the tops numbering system number 70 and above was traditionally for electric traction.
It'll be interesting to see who does a model of it 1st. The livery looks well, not sure about the face. A bit like an ugly but well dressed lady!
