Brutalist rattan dining chairs

Lovely set of six dining chairs with a gorgeaous oak frame and rattan seating. These chairs are very solid and in a very good condition. The frames have some scratches from the age but nothing mayor to mention. 
 
The chairs are from an unkown manufacturer but absolutly lovely! They were probably made in the 1970's in Belgium.
