You may want to change the Eli Whitney reference. While he claimed
interchangeability (as did Samuel Colt, Cyrus McCormick and Isaac Singer), he never delivered and eventually gave up. The claim was made as a distraction to investors because of financial problems with the cotton gin. The first true mass-produced interchangeable parts were actually delivered by
John Hall.
Regarding the prior claims, modern scholars David Hounshell and
Merritt Roe Smith gathered samples of the same model products, disassembled them and tried to interchange the parts without success.
