Elm Plastics was based in Motney Hill Road in Rainham Gillingham Kent. These photos show some of the workers there in the 1960s or 1970s. Can you identify any of the people in the photos? There could be a member of the Knight family in at least one photo. The Managing Director was Mr R Michalkiewicz and is mentioned in the Lower Rainham Coronation party article in 1953 as having given souvenir books to the children at the party.

Update - 4 people identified so far. Thanks to Jane Absolom, Sandra Perkins, Emma Wilson & Rachel Davis!

Back row , second from left is Hilda Hook, middle is Jean Stitt, Ethel Black on right in yellow.

Front row - middle - Jean Sabey in red 

Her friend Lil Grant will be in it somewhere

The only online info I can find about the factory is this announcement in the Edinburgh Gazette in Sept 1968:

IN accordance with Section 117 of the Factories Act 1961, the Secretary of State for Employment and Productivity hereby gives notice that, during the month ending 30th September 1968, she has made special exemption orders relating to the employment of women and/or young persons at the following Factories: Elm Plastics Ltd., Motney Hill Road, Rainham, Gillingham

They are mentioned again in 1982 for the same exemption for women and young people.
