File:Gregson and Monk Engineers Salter Road Preston.jpg

Summary
This photograph, the only one known to have survived, was taken of the historic Gregson and Monk works shortly before they were demolished. It is of interest for showing the actual appearance and scale of the buildings. The photograph's use at low resolution in an article on the history of the works is considered fair usage. The image itself is shown on a historical society's website and is not used commercially, but in any case the low resolution employed here ensures it could not compete with any possible future commercial usage.
