Dollis Hill Trials

In the 1950’s the postal system was radicalised by the Dollis Hill Trials into phosphor ink, which has the purpose of improving how postage was sorted. The Dollis Hill Trials where tested on Wilding Stamps and in turn revolutionised the design of the sorting of all future mail.

Maybe you are a collector of Wildings and would like to know more about why the Wildings with Multiple Crowns are available with different coloured varieties of phosphor ink? Perhaps you are intrigued with stamps and would like to know more about their history and the development of the stamps we use today? Well this YouTube Video will be an ideal watch as it is very informative and offers interesting facts about both the Trails and the Dollis Hill Building. For example, the experimentation of phosphor or the Dollis Hill building’s role in winning the second world war.

Not only is this YouTube Video brilliant for creating an informative picture of the Dollis Hill Trials, it is also a useful tool for collecting Wilding Postage Stamps as it gives examples of what Phosphor on a Wilding might look like.
