Here is a little information regarding Harrington & Richardson, source may be suspect though.
"The original H&R firm was in business for over a century from 1871 to 1986. Its roots are deep in the mid-19th Century Connecticut Valley firearms industry where the Wesson brothers loom large in the history of American firearms innovation. Edward Wesson was a noted maker of fine percussion rifles. Daniel B. Wesson was the co founder of Smith & Wesson, and design genius behind many of their break-through innovations.
Baby brother Frank Wesson started his own firearms manufacturing firm in 1859, sharing an early patent with Nathan Harrington. Wesson produced his famous two trigger rifles and spur trigger pistols and pocket rifles. He shared a brief partnership with his nephew Gilbert Harrington, as Wesson and Harrington. In 1875 Harrington and another former Wesson employee, William Augustus Richardson formed the new H&R company. In 1888 the firm was incorporated as The Harrington & Richardson Arms Company. The capital was $75,000. Harrington was president, Richardson was treasurer, and George F. Brooks was secretary. After the deaths of Harrington and Richardson, Brooks became the manager. Both Richardson and Harrington died in 1897. Harrington died on June 22, 1897 Richardson died on November 21, 1897. He lived at 921 Main Street in Worcester.
In 1894 the company opened a new facility on Park Avenue in Worcester, Massachusetts to respond to customer demand for their products. H&R was enjoying such success that the factory was expanded again after only a few years.
In the 1960s it was owned by the Rowe family, and warranty cards were sent to 'Industrial Rowe', Gardner, Massachusetts. The old H&R Company went out of business in 1986, and the building, a five story brick structure, which was located at the corner of Park Avenue and Chandler Street in Worcester, Massachusetts, was demolished. A Walgreens pharmacy now stands at this location.
A new company, H&R 1871, Inc., was formed in 1991 and started production of revolvers, single shot rifles and shotguns using old H&R designs. H&R 1871, Inc. assets were sold to H&R 1871, LLC, a Connecticut LLC owned by Marlin Firearms in 2000. Unfortunately for owners of old H&R firearms, neither Marlin nor H&R 1871 will have anything to do with the older H&R guns as regards to parts and information."
