Eli Terry was using interchangeable parts using a milling machine as early as 1800. Ward Francillon, a horologist, concluded in a study that Terry had already accomplished interchangeable parts as early as 1800. The study examined several of Terry's clocks produced between 1800–1807. The parts were labelled and interchanged as needed.
Hall recognized individually fitted parts as the factor slowing rifle production and adapted his breech-loading design to the “uniformity principle,” widely known as interchangeable parts. Hall proposed the concept of interchangeable parts to the Army in June 1816 [ 1 ] and earned a contract for 1,000 of the "Model of 1819" Hall rifles from ...

Colt's great contribution was the use of interchangeable parts. Knowing that some gun parts were made by machine, he envisioned all the parts of every Colt gun to be interchangeable and made by machine, to be assembled later by hand. His goal was an assembly line. [18] This is shown in an 1836 letter that Colt wrote to his father in which he said:
Henry Martyn Leland (February 16, 1843 – March 26, 1932) was an American machinist, inventor, engineer, ... including the use of interchangeable parts.
Blanc, and the interchangeable musket parts experiment, is highlighted in a multi-page footnote in Mémoire sur la fabrication des armes portatives de guerre by Gaspard Hermann Cotty (1806). [5] There were "50 or 60" rifles and LeBlanc first developed the technique in 1777, demonstrating it just before the French Revolution.
