Penistone Foundry opened as the Yorkshire Steel and Iron Works, an extension to the original site to the north of the rail tracks (HSY6057). Shown on 1931 maps. Its use was initially short lived as the site was closed in the 1930s following the Wall Street crash. The site was unused for five years but then bought by David Brown Co. to make steam turbines (Hey 2002, 163-164). Still in use as an industrial site. Previous strip fields subsumed by the industrial complex therefore legibility is invisible.
