Victoria Tin Plate Works, also known as Villiers Works after the owning company, are shown and annotated on the Ordnance Survey 25-inch second edition map of 1899 (but not on the first edition of 1880). Also shown, adjacent to the south, are the Gwalia Tin Plate Works (nprn 309216). On the third edition map of 1918 both works are shown but neither is named and on the fourth edition of 1937 Gwalia is shown to the north of Victoria - this is almost certainly a mapping error.
