​The company was not a large enterprise like Colt or Sharps, but it employed what seemed to be a lot of people in the small city of Hamilton. At the height of its production, it employed around 102 to 125 men, each specialized for a specific task in manufacturing, such as carpenters, blacksmiths, gunstokers, strikers, and a polisher.6 One can assume that the production had gradually increased over time as the company’s machines and workers became familiar with the new design. Yet, production capacity would never reach the production levels of larger firms, especially at this time due to the company hand fitting the carbines instead of using mass produced interchangeable parts. Other larger firms would have had more machines, possibly of greater capacity, that would allow for a faster production process. Similarly, companies who used steam, such as Sharps and Colt, were able to power their machines regardless of bad weather, making their production rate more consistent.



The Gwyn & Campbell Company officially ended around November 16, 1868, after the death of Abner Campbell.7 After Campbell, who would have had connections due to his family’s prominence, died, the company may have lost its financial supporters. However, the company’s road to closing started after the war when they failed to gain a government contract for their carbine designs, both a single shot and a repeater, and even a contract to repair federal arms. In 1866 to 1868, the company made “patent broom heads” to maintain some profit, but ultimately it was not enough.8 The Gwyn & Campbell Company was one of many firms that did not survive long after the war, regardless of their accomplishments during it.8​
