- A new and fully-priced listing of Indian stamps used in Kuwait.
- Several new plate flaws and watermark varieties have been added to Great Britain and many Commonwealth territories.
- Further prices have been given for high face-value stamps with fiscal cancellations and a start has been made (in India) in pricing telegraphically used stamps.
