How many muskets were made per year before interchangeable parts?

Before the introduction of interchangeable parts in the early 19th century, the production of muskets was a labor-intensive process, with each musket often being handcrafted by skilled artisans. Typically, around 10,000 to 15,000 muskets were produced annually by major armories like the Springfield Armory in the United States. However, production rates varied significantly based on factors such as demand, technological capabilities, and the specific time period. Overall, the lack of standardization meant that manufacturing was less efficient compared to later methods.
