Mr. Snyder:

You are most welcome and this is a venue where I can sort of keep tract of what I've found. I hope we find some info or draw some conclusion on the types of tube steel. I really didn't intend to get side tracked on American steel but Krupp Nickel led me to either Sanderson or Crucible Steel Company of America and here we are. A neat diversion.

"Brand for tool steel, “Crown.”(Formerly operated by the Crown and Cumberland Steel Company)." - http://books.google.com/books?id=fS4qAAA...aryland&lr= . For now I thik this to be the source of our evasive "Crown" tube steel.

The Crown and Cumberland Steel Works, near the main line of the Baltimore and Ohio Railway, were built by local capitalists in 1872. The manufacture of tools and spring steel of superior quality is an extensive part of this business. The iron is procured in bar form and melted. Rollers of various sizes and an enormous steel hammer, with a striking force of five tons, are included in the equipment of the works. The peculiar qualities already noted of the Cumberland coal render it of especial value in the making of steel. About seventy men are employed by this company. The capacity of the works is ten tons of steel daily. - I can source it if need be.

And of course Crown & Cumberland, along with Sanderson, was folded under the Crucible Steel Works umbrella circa July 1901:
