Consider the guns that Pinfire has been featuring in his British gun thread. Beautiful pieces made by master craftsmen. The Birmingham gun trade, and the Belgians also produced untold thousands of modestly priced guns for export. But they were still lock, stock and barrel guns. Cheaper, less finished, more quickly assembled, but still traditional guns.
This gun is at the opposite end of the spectrum from the fine European guns. It came out of a factory that was using machinery. There is no pretense of traditional craftsmanship. It was designed for factory production. It was intended to sell at an affordable price to someone who needed a working gun, and who did not care about style or elegance. 19th century industrial technology.
