I have absolutely no science or evidence to support the statement I am about to make but I am going to say it regardless...
It is my guess that the tolerances allowed in manufacturing during the late 1800s through the early 1900s were not even as close as what we would see from current metallic 3D printing media.
"Back then" machines were calibrated by hand using calipers and measuring tools that were also calibrated by hand. As good as those machinists were at what they did, they simply cannot compete with the piece-by-piece accuracy of a computer program. Digital is always more accurate than analogue, especially when it comes to making and producing replicated items.
But that is just an uninformed guess-turned-opinion...
