An exhibit at Bruce Castle Museum charts the history of the Postman.
M/S of a man in an old-fashioned (pre-1840) postman's uniform and using a dimensurator to measure mileage; commentator explains that postal charges once depended on distance. We then see various shots of exhibits in Bruce Castle Museum that illustrate the history of the postal service; models, uniforms, guns that the postmen used to be armed with for protection against highwaymen.
A man in an old postman's uniform is seen weighing a letter on a tiny scale; there are models of every kind of transport that has carried the Royal Mail: stage coaches, ships, aeroplanes.
Note: on file is correspondence and general notes on Bruce Castle.
