Circa 1900, several U.S. of A. makers offered double barreled guns with "Crown Steel". From some of the pre-1900 Sears & Roebuck catalogues and other ads, the 1st offerings may have been as early as 1894/1895. Whiteley Steel Company of Muncie, Indiana was incorported on December 20th, 1897 and they used the traded name "Crown Steel" on tool steel and possibly steel for auto, which was a mixture of imported ingots or imported ingots. But I think they were a little late to the party. Another option is the Crown and Cumberland Steel Company of Maryland. Does anyone have any info on the "Crown Steel" tubes. Interesting how other steel offerings were blue steel, Rolled Steel(Winchester), Crown Steel, Ordnance Steel, Krupp steel, Whitworth Steel, etc. with the component percentages being a secret.

Kind Regards,
