Roche Products Ltd, which acquired its Welwyn Garden City site in 1937 and opened its factory in 1938, has kindly donated a collection of 18 photographs to the Where Do You Think We Worked? project from its archive.
These pictures were taken during the War Years when Roche's offices in Broadwater Road became the home of the 4th Battalion Home Guard.
More of the collection can be seen by finding the Trust on Facebook. Click here to visit.
