I have a 15th Impression 1965.
The printers made a mess when they set up the type for the printing history on the Third Edition 1966:
What should have read as:
Fifteenth Impression 1965
Third Edition (Sixteenth Impression) 1966
was actually set down as:
Third Edition (Fifteenth Impression) 1966
Sixteenth Impression 1966
This error was never corrected.
The Third Edition includes four colour plates rather than one, and remained the same up to 1974 when they reset the text and added another colour plate.
