Royal Mail Special Delivery from 1971
IntroductionHistory: Following on from my display of Post Office Inland Express Delivery 1891-1971 it was felt that the service for Post Office [Royal Mail] priority mail should be extended beyond 1971 to more recent times [1998-99].
The key dates of interest during this period are :-
 the introduction of Decimalisation in 1971,
 the rebranding of the Special Delivery in 1980.
 the introduction of barcoded tracking in 1993.
Note: Royal Mail used the term Guaranteed Delivery on their Special Delivery labels from 1993 until 1996 as mail was guaranteed delivery next day by 12.00 Noon
 and the end of the Registered Letter Service in 1998 when Special Delivery became the priority service for a Next Day delivery of items of value or urgency.
The Display: Shows mail and associated 'over the counter' items such as certificates covering the 28 years from 1971 to 1998-99. Material from this period is not easy to find and the only sense to be gained is to build up a reasonable collection and select representative types of label use, and the various fees and rates during the period of rapid inflation.
This two frame display should be studied together with the development of the Express Service prior to 1971.
The only detailed reference that has been found in regards to the RMSD Service is the article that appeared in Gibbons Stamp Monthly in February 1990 Royal Mail Special Delivery -- A closer look by Conway Longworth-Dames. [this gives the label types a classification]
Feedback on any aspect of the display would be welcome --
