Then Jif ...
Maybe even let Wilts and Dorset (sorry, there we go again, let "Salisbury Red") know, they don't seem too sure.
You might like to muse over the differences in timings for the 1725 journey from Marlborough as per Salisbury Red and Traveline; and whilst so musing think about the effect of the various notes on the "Red" timetable and, in turn, their effect on passengers relying on Traveline and waiting at, say, Milton Lilbourne at 1739 to go to Pewsey.
Or the 1746. Or the 1806?
A quality "Salisbury Red" brand?
