Lot of six vintage school chairs

Lot of six vintage 1980s school chairs probably, brown metal tubing... Vintage state, I.e. Many traces and wear of time and use. Confer photos. Note that a chair has three missing tips on the footing, four folder tips are missing and two rivets on a folder have been changed. Beautiful patina... Stable, solid, clean and oiled by us. Standard seating height of 45cm. Height at the back of 77cm. Floor clutter of 36 cm of façade by 56 depth. Gerbables, these six chairs will find a place around a bistro or farm type table.
