Having realised the importance of patching (see article in Sheetlines 132) Dr. Rob Wheeler started looking at the early history of the series and how the printed sheets relate to the plates.  He believes the results are instructive.  He plans to end by explaining how a country on one projection - Scotland - can be joined to one on another projection - England - or perhaps how it ought not to be done.
