Cotty, H. (1806). Mémoire sur la fabrication des armes portatives de guerre [Memoir on the manufacture of small arms of war] (in French). Paris, France: Magimel. p. 73, footnote. From p. 73: "Il n'est peut-être pas hors de propos de rapporter ici que je tiens de personnes dignes de foi que, quelque tems avant la révolution, le sieur Blanc, […] à qui on doit particulièrement l'avantage de l'uniformité dans les équipages de l'artillerie.)" (It is perhaps not out of place to report here that I have learned from credible persons that, some time before the [French] Revolution, Mr. Blanc, [who has been] already cited, presented to the Minister fifty or sixty [gun] locks from the stamping machines, established at great expense in Vincennes by the government of the time, which were beautiful and well formed (it is believed that nothing was spared). They, [as well as locks] from several muskets, were dismantled and the parts mixed in the presence of Mr. de Gribeauval, [who was] at that time first inspector general of the artillery, and then one took at random a certain number of pieces — [which were] combined to construct a [gun] lock — in which the defects of fit were soon recognized. (If this [method of] production seemed abandoned from its birth until 1793, would one not be permitted to believe that Mr. Gribeauval, who could not be deceived by seductive innovations, sensed the impossibility of this identity [i.e., that it was impossible for machines to produce identical parts]? He, moreover, to whom we particularly owe the advantage of uniformity in artillery.))
