In the hopes of helping those seeking to remove the body/shell/jacket* of a Corona Zephyr (1938, in this case), I've created a step-by-step process based on my recent experience. (\The user manual from the 1930s refers to the machine's body as a "jacket.")* The steps are: Remove the two screws underneath the keys at the front of the machine (holding the typewriter to the base of the body. 2, 3, 4. ON EACH SIDE, remove the screws at positions #2 & #3 and the lug nut at position #4. Don't remove the screw at position #4 as it's not necessary & will be difficult to set back in place. Remove the back lower panel of the body to reveal the screws at position #5. Remove the screws at position #5 from EACH SIDE of the machine. Using a thin piece of cardboard (I used the cardstock from a cereal box) or a stack of a few pieces of paper, depress the top row of keys so that they'll slide under the body as you slide it forward. Slide the body forward, slightly lifting the back end to help guide it out. Work slowly & gently, keeping an eye on the keys to ensure that they are not getting caught on the body & that nothing is getting crushed, scraped, or scratched as you work. Continue gently & carefully sliding the machine out of its body. A view of the body without the typewriter within. Note that it is a single piece and the top & bottom do NOT separate. Good luck! ALSO: this guest post from Garrett Lai on Richard Polt's Typewriter Revolution site has a good approach for aiding in the sliding of the typewriting in & out of the body by making some plastic skids to avoid scraping/scratching during movement: https://writingball.blogspot.com/2020/06/guest-post-disassembling-smith-corona.html If you want to get any Corona Zephyr servicing details from the source, be sure to see Theodore Munk's post which includes his insights along with a copy of the original "1938 Corona Zephyr Typewriter Service Adjustment Methods" manual: https://typecast.munk.org/2023/02/11/1938-corona-zephyr-typewriter-service-adjustment-methods/

Hi friends! I received a vintage teal blue SCM Smith Corona "Skyriter" typewriter. It is awesome, but it does not have the original spools. I ordered an expensive original ribbon from eBay, but it was totally dried out. Then I ordered an inexpensive "universal" (2") spool from Amazon that didn't fit in my machine. Does anyone have recommendations of new, small spool (1 5/8") ribbons that tend to be reliably inky? I am located in Canada and getting tired of paying import costs on stuff that doesn't work. Thanks in advance!

We also now stock the smaller Smith Corona TW15 spools for models such as the Calypso, Corsair, Skyriter, Ghia and Zephr.

Corona had a part number for the sheet of cardboard you’d use to press down the top row of keys before removing the shell of the Zephyr: Part No. ST1243, and it cost 25 cents.
