Comes with user manual.
The manual says Selectric II, but the typewriter is III.
For parts.
Powers on. Space bar works. Return key advances the paper but doesn't return the carriage. The shift and a few other keys in that area are pushed down.
Various keys don't do anything. Press other keys and the typewriter will suddenly rapid type 20 or so letters on its own before stopping. And the "letters" it types are just dashes.
Most of the pictures have the cover raised. It does have the cover. Can see it in a couple pictures.
