In 1932, entrepreneur Max Wiseman imported into the UK an entire factory of spectacle frame-making machinery and staff from Germany.

The Algha Works factory was born at Fish Island in east London and fast became a leading manufacturer of frames, including the eternally fashionable "round-eye".

Now the only frame maker left in Britain, the factory is still in business today producing glasses under the Savile Row brand - and mainly exports its products.

The original machines are still used to hand-craft the spectacles, which have been worn by the likes of Harry Potter, Denzel Washington and Johnny Depp.

Staff old and new reflect on the history of the plant and what it is like working with antique tools and machines, which each have a personality all of their own.
