Actually, no. If you were to hand someone a typed document, you would not know "Ah-hah. I can tell by the e that is precisely 3 nanometers above the line, and the slight smudging of the ink on the qs, that this was written by Joe Schmoe's typewriter, which I have "registered", but which I otherwise do not have access to". You say it yourself; typewriters "develop" quirks, in addition to any they start with, meaning that even if you had collected samples of every typewriter at the time of sale, and had a way to compare a document against all of them (despite this being pre-computer, given the prevalence of typewriters), you would not be able to find a match.
What -you- are describing, is "Was this particular document written on this particular typewriter", which is possible by comparing it against a document you know to have been written by that typewriter, and which I detail in my answer which you didn't fully read ("That (...) would allow you to examine specific typewriters. You may be able to determine a letter was written from a -given- typewriter").
This is identical to ballistics; finding a fired bullet does not tell you the specific gun that fired it (but may tell you the model/make; certainly, it will tell you the type of ammunition it takes). But if you have a bullet of known provenance (i.e., one you fired from a suspect's gun), you can tell if the markings left on the bullets match.
