Other than a marketing ploy, why would one want "Sheffield Steel" tubes instead of a local name steel type? Can you really imagine 500k tubes being held to one of those large grinding wheels each year? Tube makers were a hardy lot and in the gunmaking centers I think that a handful of certain families were sourced for tubes.
Do not think as an American. No ploy involved. They were located in Sheffield. The trade name is Andrews Toledo Steel works. Toledo swords are some of the finest in the world. They were of course produced in Toledo, Spain.
Wiki I bet you were looking in Ohio
They are listed under hammers in an 1895 source as an importer of goods into western Australia. But this was just a side line. They were a steel producer
