Elegant set of six Italian dining chairs

What a stunning set of dining chairs!
 
These six dining chairs are made in Italy but from an unkown manufacturer. They were probably made in the 1970's and are a perfect example of Italian craftmanship and quality! They still have the original cognac leather seating. 
They are in good condition but have some signs of age.
