Olivertti Studio 44 typewriter

Azerty keyboard. Ing. C. Olivetti e c, s.p.a ivrea. Madi in italy. No transport box. The ink ribbon is new. The machine works. Color / green and dark grey. The lever arm (back to the line) has a broken spring. Therefore the lever works, but does not automatically return to the original position. It must be accompanied manually to bring it back into position. Otherwise everything else works perfectly.
