Set of bistro chairs

Set of 10 mismatched beech bistro chairs, each is unique and fully aerogumed. They have no manufacturer identification but their manufacture would be between 1955 and 1970. They are therefore raw and just need to be patinated, lacquered, varnished or waxed. They are in their juice (wood defect and dark shade in some places) with, for two of them, some small galleries on the seat (see photo), which does not imply any defect in solidity. They are all very stable and no foot is attacked, in a very good condition for their age and use.
