Casgliadau Arlein

An illustrated catalogue of tools and equipment used in building and engineering trades e.g. hammers, spanners, wrenches. The catalogue has been signed by Mr Hugh Richard Jones who was Chief Engineer at Gilfach Ddu between 1966 and 1969 (the last before Dinorwig Quarry closed in 1969), and who was instrumental in saving the fixtures and fittings of Gilfach Du in order for a museum to be set up in the old quarry workshops.
