Best Answer

Diamond Arms Company and Nitro King are both trade names used by the Shapleigh Hardware Company of St. Louis, Missouri. Some of the guns were imported from various Belgian sources, but they were also made by W.H. Davenport Firearms Co (1890's - ), Iver Johnson Arms & Cycle Works (early 1900's - ), J. Stevens Arms (before 1942), and Savage Arms.

If there is an oval with ELG* stamped on the barrel or action, it is from Belgium. If it is a 410 that's unlikely, and that would also eliminate Davenport as the maker.

If it says Armory Steel that suggests that it MIGHT be an Iver Johnson Champion.

Most of the Belgian imports stopped coming over when WWI started.

Add Crescent Firearms (1893-1930) to the list of manufacturers. If marked model 94, it's a Stevens up to 1948. 944 will be the same gun from Savage after 1948.

I have a King Nitro, but it is a 22 pump with an octagon barrel, made by the Central arms company. I have never researched it but have always been curious about it. I would be interested in further information if available.

Where can you find information about a King Nitro shotgun by Central Arms Co?

Both 'King Nitro' and 'Central Arms Co' are trademarks of the Shapleigh Hardware Co, which was a major catalog retailer from the late 1800's well into the 20th century. The shotguns marketed under that name were made for Shapleigh by different companies, notably Davenport Firearms, Crescent, Hopkins & Allen, and Stevens. We'd have to see the shotgun to determine which manufacturer actually made the shotgun.

What are facts about Shapleigh's King Nitro 12 gauge shotguns?

Diamond Arms Company: Trade name used by the Shapleigh Hardware Company of St. Louis, Missouri on imported shotguns they retailed. WWI pretty much ended these imports and later guns may have been made by any of several US companies. A single shot is possibly an Iver Johnson Champion, a double barrel likely to be by Crescent or Stevens. There is little collector interest in these old utility guns and shooters would rather have newer firearms, so they are not highly valued. Singles sell for $50-$75, doubles for $125-$150.

Is King Nitro the store name for a Stevens or Savage model of double-barrel shotgun?

As I saw in other faq`s answered about King Nitro shotguns, they were made by Sears,Roebuck co. We need to find those other answers and correct them. Sears Roebuck never made any guns unless you count those manufactured by their subsidiary company, Meriden Arms from 1905 to 1915. Nitro King was a Sears brand but King Nitro was a trade name distributed by Shapleigh Hardware of St Louis. The guns were made by W.H. Davenport, Iver Johnson, J. Stevens (model 315 double barrel), and unidentified Belgian manufacturers.
