Two keys are sticking — the Q and the M. ALSO, the roller does not advance as you hit the keys. If it’s possible to lock the roller, it may be locked. Or it no longer works. I have no clue. Comes with key and brush for Smith Corona, as well as correction tape (no idea if it still works but it might) and a Remington Instruction manual. Will need to install fresh ribbon for typing (there is an old ribbon currently installed).
