    1. An article from American Machinist Magazine (January 4, 1923). The article, "The Organization and Management of a Medium Sized Plant," was written by Percy S. Brown, a Works Manager at The Corona Typewriter Company in Groton, NY. He would become vice-president of Corona in 1924. Here's a snippet on what went into making one Corona typewriter. "There are 671 parts on the typewriter, 139 on the case, 110 on the folding stand, a total of 920 parts. There are 355 different parts on the typewriter, 61 on the case and 37 on the stand, a total of 453 different parts. There are 1,999 manufacturing operations on the typewriter, 210 on the case, and 205 on the stand, a total of 2,414 operations, exclusive of inspection. To these must be added 38 subassembly operations and 15 assembly operations, a total of 53 assembly operations, and a grand total of 2,467 operations of all kinds, exclusive of inspection. If inspections are added, the total number of operations performed amount to approximately 4,600."

    1. A typewriter contains approximately 1800 to 2000 parts, which require approximately 20,000 different operations to manufacture. An operator typing at the rate of sixty words per minute actually motivates, with his or her fingers, 10,000 to 12,000 parts per minute, approximating 200 moving parts per second.

    1. Like most Hermes Rocket/Baby typewriters, mine no longer had feet on the bottom. You can purchase 3D-printed feet at various places, but I went with the silicone grommet/cap route and found a perfect fit. These are rubber caps meant to replace the cushion on the bottom of certain furniture. The holes on the bottom of the typewriter are 6mm in diameter. These plugs fit tight, provide a slight lift, and a slip-free typing experience. I did have to trim off the tops a bit to fit the body back in, but that's all inside the typewriter when put together. These were a pack of ten for $6 USD (or .60 each).

    1. reply to u/EdmundDante718 at https://reddit.com/r/typewriters/comments/1o5x527/missing_carriage_releases_on_scm/

      It's incredibly common for these 6 series Smith-Coronas to have broken plastic carriage release levers (a major design flaw). You can call around to shops with parts machines for original replacements. https://site.xavier.edu/polt/typewriters/tw-repair.html

      There are numerous YouTube repair videos and ideas including these few I've bookmarked before, though there are surely others: - https://www.youtube.com/watch?v=zNcQvfUk23s - https://www.youtube.com/watch?v=Gb9VlrKcXcM

      I've not seen anyone 3-D print a version (yet), but designs for one might be floating around out there.

      I've also seen people jury rig all sorts of plastic replacements which is an option as well.

      In practice, you generally only need one working one for your dominant hand.

    1. The long, thin spring-loaded metal flap labeled the "paper conductor" on the SM3 and SM4 and labeled the "erasing table" on the SM2 are all the same part. They serve a few functions.

      They can be used for erasing mistakes certainly and help to keep dust and debris from going into the carriage and rollers.

      The "paper conductor" description sounds like a fun translation of something from German into English, but this part also prevents the paper which goes under the paper bail and forces it up and back to the paper table and the paper support. Presumably without it, a slightly curved piece of paper might be misrouted to go right back into the platen a second time as the paper advances.

      This sort of paper conductor/dust shield can also be found on some later 1960s+ Smith-Corona (SCM) machines. For example, see the Galaxie II which calls that part the erasure table.
