1952 Smith-Corona Skyriter (2Y Series)
This Smith-Corona Skyriter is a little rusty, but it still types like it's new somehow. There's some light rust on the sides of the machine, some deeper in the typewriter, and a good amount of rust on the case, however none of that rust is doing anything to get in the way of the functionality of this little workhorse. It's extremely portable (in fact, it got the name Skyriter because it could travel easily and could be used while traveling by air back in the day)
Overall, this isn't the greatest option for heavy use, but it can be used frequently and should last awhile with proper care despite the rust.
