PERSPEX, the acrylic sheet product which changed the world, has been manufactured in Darwen for nearly 70 years — and still is.

During that time thousands of local people have been employed in its manufacture, sale and distribution and many will have memories of their working days there and photographs of colleagues, the product and the works.

Now the Perspex team at the Orchard Mill and Chapels Park factories want to see your photographs and hear your recollections going back through the last seven decades.

For this year Perspex celebrates its 75th anniversary, after it was first registered as a trade-mark on November 16, 1934.

As part of the celebrations to mark its birthday, the Perspex team is hoping that the people of Darwen and surrounding areas will dig through their memories and hunt through their old photos to come up with personal stories, recollections and photos of how Perspex was used, made or had an impact on their own or the town’s life.

You may be a former worker, or maybe a local customer, a signmaker or fabricator with some interesting tales and pictures — it doesn’t matter — Perspex would like to hear from you.

The names of all those who supply a photo or story will be entered into a prize draw to win a limited edition Perspex draughts set and some 75th anniversary memorabilia, but you must get them in before Friday, November 13.

You can send them FAO Val Houghton at Lucite International, PO Box 34, Orchard Mill, Duckworth Street, Darwen, BB3 1QB or val.houghton@lucite.com.

If you would like your photographs returned, include a stamped, self-addressed envelope.
