My guess is not very long, since these machines were stretching mechanical eng state of the art when new and were not that reliable either. A lot of heat treated steel parts, precision bearings and fine adjustment tolerances etc. Played around with Teletypes and Flexowriters years ago and both could be a real pain to clean, adjust and keep running...
