Smith Corona Skyriter and Zephyr Replacement Typewriter Feet (set of 4)

Description: This listing is for (4) four replacement feet which should fit all Smith Corona Skyriter or Zephyr portable typewriters from 1949 through 1963. This machine went through 4 phases of evolution over these years, identifiable by serial numbers as follows: Zephyr: Serial number beginning with "1Y" or "1Z", 1938 through 1941Skyriter: Serial number beginning with "2Y", 1949 through 1958Skyriter: Serial number beginning with "3Y", 1956 through 1960Skyriter: Serial number beginning with "4Y", 1960 through 1963 (Made in England) I own a machine of each of these series. I found a slight variation in hole diameter between them, this could be simply tolerance, or a change between models. The original feet, made of rubber, would be a big pain to install if replacements were simply copies of the original design, requiring taking the machine apart to do so. Using advanced 3D printing design and fabrication techniques proven across my many foot designs, I was able to design a foot that fits 2Y, 3Y, and 4Y machines, and that is easy to replace, you simply push and twist it from the bottom, no need for any machine disassembly! The hard part is getting the old feet out, which in my experience meant carefully breaking them up with a screwdriver and needle nose pliers (taking slow and great care not to damage the metal case bottom!) until they could eventually be grabbed and pulled out. A drill also makes this easy! If you have plastic spudger tools that might be safer (see my last photo). Then the new ones pop right in (ok, you may need a little push assist from that last side that doesn't want to go in with a screwdriver or any safer plastic thing you can push with, but with a little patience it's easy, I did my 3 machines in 5 minutes. Now confirmed! The predecessor to the Skyriter called the Zephyr, made from about 1938 to 1941, and with "1Y or 1Z" serial numbers (mine is a "1Z"), these have now been confirmed to be the same feet and fit! See my last photo. Any other variations? The hole size should be about 12.5mm, if that matches, these feet will probably fit. Whoever wants to try a new Skyriter variation not listed, I'll allow a return if it doesn't fit. I designed these to be nearly an identical replacement, but with the advantages of modern 3D printing technology we can engineer materials that were previously impossible. I printed with NinjaFlex TPU polymer (https://ninjatek.com/ninjaflex/), which is super strong (but a knife or scissors will cut it, just like rubber!), flexible, and quite gripping on most surfaces. People that don't know any better are stating that these feet are too hard and have no grip--ignorance must be bliss. With 3D printing we can engineer material properties beyond the fundamental "Shore hardness" through complex structural design. These feet use variable internal gyroid spring structures for better shock absorption while typing, flexibility, and textured bottom surface for very good grip. Some people may prefer the original dull rubber look (and those are also perhaps being made and sold), but I actually think these are a superior look to rubber, and the glossy printing lines on the sides (only 0.2mm thick) actually reflect more light for a sophisticated glossy sheen which nicely accents the machine--you notice the lines in the photos, but in real life you just see shiny feet. I also think these will last far longer than natural rubber without compressing or falling apart, and they are precision made rather than poured into a mold with bubbles and imperfections. I designed these for my own typewriters (one is shown), and this is my ongoing experiment to see if it's worth my time to make some more for the community. Compatibility Info: Your responsibility, please don't order unless you checked! As far as I can tell, this should fit all Smith Corona Skyriters (and *possibly* Zephyrs), just confirm that they look like the photos, and measure the hole if you are not sure. This auction is only for 4 replacement feet, any other items shown are not included! Please read full description and examine photos to be sure you know what you are ordering! (sorry, I've been burned by no-read one-click buyers) PS: Ebay's volume discount display is a bit confusing, each purchase is a SET OF FOUR feet, so picking "1" is one set of 4; "2" is 2 sets of 4 (8), etc. You get one set only, everything else pictured such as typewriter and hardware is NOT INCLUDED.
