Sirs
The Centurian is too heavy for the Gramodels type warflat, as well as being out of gauge. As far as I'm aware Centurians never traveled British rail. When built most were road shipped to port and then onto Germany. Live fireing exercises were also conducted in Canada
As for modern flats I would very much like to build one but the pictures I've seen only seem to show the underside in deep shadow and therefore impossible to work out the detail. What I need is a picture of an accident, but as always you can never find one when you need it!
I'm also looking for a ramp wagon
