Vintage armchair 60/70

Old chair of the 60s it seems to me but maybe 70 I could not certify it.the cushion is made of real leather, patinated has a wish and in good condition. Note that it lacks the small button stootone (the sitting part) because they were removed so as not to hurt but we did not find them. The armrests and feet are made of wood in good condition. There is a screw setting for tilt. The receiving part of the chair is made of metal tubing covered with fabrics. The angles of the tissue at the back began to damage, we could easily put a thermostick fabric I think to hide because we did not pay attention to it. Finally note a screw is not original on one side (photo attached on this side and the second side to see the difference) Height 90 and 96 with the cushion protruding. Width 80 cm armrest on armrest. Total occupancy depth of the chair 68 cm.
