Smith Corona electric typewriter.
Coronet Automatic 10.
With case.
Old electric typewriters like this make a hum noise when on if you didn't know.
Has some small blemishes. I circled a couple.
Uppercase doesn't work.
The rest types fine.
When you press the shift key, you hear a louder hum.
You can push the big metal letter arms area (Type Bars) down with your finger, and can make it lock in that position if pushing it down while holding the Shift Lock key. It will type in uppercase then.
So, it can type in uppercase, but something is preventing the big metal letters part to move position when pressing the Shift key.
