Typewriter erika 40 blue and white 70s made in germany

Typewriter erika model 40. Made in germany. 70s (stamp dated present). Plastic cladding in blue and white tones. Touches of dark gray color. Very nice overall condition. Very rare and very discreet traces of use (discreet scratches of use in places on the plastic cladding, very rare oxidation points in places on certain metal elements. View photos and zoom). Note that the three keys (9ç), (%ù) and (̈^) tend to block after typing and require manual re-installation. The ribbon provided will have to be changed.
