If you bother to read the Wikipedia article on the Herny rifle, you'll notice that a reference is sited. You'd better add American Rifleman to the Wikipedia/Chuck Hawks list of unreliable sources!!

"In 1973, Louis Imperato bought the firearms company of Iver Johnson and began making commercial versions of the M1 carbine. In 1993, Imperato started a factory in his native Brooklyn to manufacture .22 caliber rifles
under the newly recreated name[3] of the Henry Repeating Arms Co. which are currently manufactured in Brooklyn, New York.
The current company, not to be confused with the original Henry rifles,[3] does not produce the Civil War period firearm that this article defines. It produces lever action rifles that are more akin to later Marlin types."

Here's some information on Iver Johnson (from Wikipedia
)
"Iver Johnson died in 1895, and his sons took over the business. Frederick (born 10/2/1871), John (born 6/26/1876), and Walter (birthdate unknown), had vastly different levels of involvement in the company ranging from executive leadership to barely any involvement at all. They shepherded the company through a phase of expansion, as bicycle operations grew, then converted to motorcycle manufacturing and sales. They also saw the growth of the firearms business and the eventual restructuring of the company to focus on firearms and related business as they divested non-firearms concerns, such as the motorcycle business, in the face of growing firearms demand, World War I's armaments industry expansion, and other factors. As family ownership waned and outside investment via publicly traded stock and mergers/acquisitions/partnerships took hold, the company changed ownership and moved several times during its operation. The company eventually dropped "Cycle Works" from its moniker when that part of the business was shut down. The business successfully weathered the Great Depression (in part thanks to higher rates of armed robbery crimes, which helped maintain demand for personal firearms) and was buoyed by the dramatic increase in the market for arms leading up to and during World War II. As a result of changes in ownership, the company had the first of two major relocations in 1971 when it moved to New Jersey.
It moved again to Jacksonville, Arkansas, and was jointly owned by Lynn Lloyd and Lou Imperato, who also owned the Henry brand name, before it finally ceased trading under its own name in 1993, at which time it was owned by American Military Arms Corp (AMAC)."
