In the 18th century, the concept of interchangeable parts was put to the test in an interesting way. The French military presented a challenge to the inventor of the interchangeable parts system, Honoré Blanc, to demonstrate the potential of his new system. Blanc was tasked with taking apart a musket and then reassembling it with parts from other muskets. To the surprise of the French military, Blanc completed the challenge successfully using only parts from five other muskets to assemble a sixth musket that worked. This demonstrated the potential of interchangeable parts and helped to revolutionize the way that products were manufactured. This story was reported by The Guardian. Source
