This listing is for a set of 4 replacement typewriter feet which will fit a variety of Smith Corona typewriters made between 1949 to 1964 which use 25mm x 25mm x 14mm cube-shaped feet which slide mount between metal prongs. Please examine the photos carefully to be sure this is a match to your machine, they are easy to spot with their simple square footprint. For the most part, if the serial number begins with a 5, it probably uses these feet. The exception I am aware of is the 5 series electric models, which have different feet. I have each of these machines myself, and used TWDB to compile the compatible list of 5-Series machines, serial prefixes, and range of manufacture dates as follows:
The 1/2/3/4-Series typewriters, as well as later 6-Series machines, share many of these model names, but the feet are different. Be sure your serial number begins with "5" as per above, and look for the size and shape as shown--basically squares that push more easily inwards into the mount. Foot replacement with these feet is dirt simple--just pry out the old ones, and carefully push in the replacements. In both directions, use an alternating back and forth wiggling from side to side, being careful not to puncture the feet on the sharp prongs as you do so (the feet are super strong, but I am careful anyway). You have two installation choices:
These machines are somewhat "young" by typewriter standards, and Smith Corona somewhat uniquely used a rubber in the original feet that are miraculously still flexible on all of my own specimens (rather than the hard, crumbling, or melting feet on nearly every other old machine). This may be fine for the shelf or casual use, but sadly while they look ok, they probably have no traction at all, so the machine will slide around making typing difficult. They might even mark up your table, or the sharp prongs may scratch it if they are compressed at all.
This auction is for replacement and much improved feet using modern 3D Printing techniques and synthetic materials, I think they look and function better than the original rubber ever could have, and will hopefully last a lot longer! I designed these to be nearly an identical replacement, but using the advantages of modern technology to engineer materials that were previously impossible. I printed with NinjaFlex Black TPU (https://ninjatek.com/ninjaflex/), which is nearly indestructible in ordinary use (but a knife or scissors or sharp mounting prong will cut it, just like rubber!), flexible, and very gripping on most surfaces. I printed these with a complex internal structure alternating gyroid infill (for flexibility) with solid layers (for strength), for a balance between strength, tight fit on the machine, shock absorption, and incredible grip. These look and function much like the original, but should last much longer and be far more durable. Some people may prefer the original dull rubber look, but I actually think these are a superior look to rubber, and the glossy sheen looks great accenting the machines. Rubber hardens within a few years, these should not!
I designed these for my own typewriters as shown, and this is an experiment to see if it's worth my time to make some more for the community. Please ignore other's marketing claims that 3D printed feet have no grip, or that their feet are more "professional". Look at my reviews, these are beautiful and amazing typewriter feet being bought by collectors and dealers alike, I'm regularly told my feet are the best.
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.
**PSS** Typewriters and any mounting hardware shown in photos is for illustration and display only, and is NOT included in this listing!! This auction is for sets of 4 typewriter feet only**
