This is interesting.
In 1911 Hopkins & Allen listed the Ladies Model (Single) with Decarbonized Steel.
The No. 112 Hammerless was still listed with American Decarbonized Steel in 1918.
Single barrels were also listed with Diadem Smokeless Steel (
Researcher likely knows which models? ) as was the Marlin Model 60 single in 1923.
Ive found no Iron & Steel Works that used the Diadem name. Interestingly, there was a Diadem Manufacturing Company, Mfrs. of Celluloid Novelties in Fitchburg, Mass.
"Crown" was the brand name of the Crown and Cumberland Steel Co., Allegany County, Maryland which was established in 1872. Related to the Panic of 1893, Crown and Cumberland Steel was sold at a trustee sale in 1894, and then reorganized as Cumberland Steel and Tinplate Co.
In 1901, the company became part of Crucible Steel
http://www.crucibleservice.com/history.aspx Hunter Arms first used "Crown" steel with the introduction of the Pigeon Gun in 1893, with barrels surely sourced in Belgium.
c. 1901 - 1903 Ithaca Gun Co. No. 3 and above models have been identified with Crown Steel marked on the top of the barrels
In the 1900 Edition of
The Horseless Age, Volume 7, Whiteley Steel Co. of Chicago with works in Muncie, Indiana also advertised Crown Steel
