Fry's was founded in 1728 in Bristol and shipped chocolate worldwide
Back in 2007, the BBC Bristol website debuted a fascinating film showing life inside the Fry's chocolate factory at Keynsham in its 1930s heyday.
The unique insight is courtesy of Bristol film historian Bryan Haynes who holds the 16mm footage in private archives at his home.
The Bristol firm was founded in 1728 and by the late 19th Century it had grown to employ some 4,500 people.
In 1921, all of Fry's business was transferred to the Keynsham site, before the company became part of Cadbury's in 1936.
In 2007, Cadbury announced it was to close its Keynsham factory with the loss of around 500 jobs.
Staff in Keynsham were told during an emergency meeting that the phased closure would begin in 2009, with production moved to factories in Poland and Bournville near Birmingham.
Cadbury was taken over by US food company Kraft at the beginning of 2010, after its board approved a new increased bid.
In February 2010, Kraft announced plans to close the Somerdale factory, despite saying that it would keep it open.
