Earlier today I posted a reply on the Scalefour Soc forum showing how to add contour lines to the historic 25" maps from NLS. It may be of interest:
If the contour lines are included in the printed templates, scenic formers can be cut to match them when building up the model scenery. That could be useful in 2mm scale -- maybe less so in 7mm in the absence of a barn.
That assumes of course that the modern contours haven't changed over time, although hills and valleys tend not to move around much unless there have been major infrastructure developments.
