Thanks Ruddingtonrsh56, l too am concerned how the 47xx would look. I believe the current Project thinking is to mount a No.7 two inches lower to avoid the excessive height of the original. This is probably with a view to retaining mainline aspirations. I am not sure if the cladding would retain the look of the production series which is l think what most people want to see. I think the No.1 option would also be clad to retain this form .
