Mevril Bleach Works

Another picture from Mevril Bleach Works.  This group photograph is from the 1950s. Does anybody know what the occasion was or who these people are? The works, at Horwich End, closed in the early 1960s.

Peace Day

Although hostilites ended in 1918 and November 11th is each year marked by the Festival of Remembrance, the First World War did not officially come to an end until the signing of the Treaty of Versailles on 28th June 1919. The event was celebrated on 19th July when Peace Day saw processions throughout Britain. In Whaley Bridge, a float is photographed outside Mevril Bleach Works at Horwich End.
