1912: A one-sheet oddity
The 1-inch Fourth Edition of Scotland used survey information from the third national revision of 1910, which was abandoned. Only one sheet in the series was published: sheet 26, covering a small portion of Berwickshire and Roxburgh, although the vast majority of the sheet consisted of England and was thus left blank!
The series was superseded by the introduction of the 1-inch Popular Edition of Scotland.
