Pair of metal tube chairs industrial furniture early 20th century

The chairs are in very good condition. In curved steel tube, made in france from the first half of the 20th century. They were repainted a long time ago, and are now patinated by use, which gives them a crazy charm. You have to look at the pictures, the bottoms of the feet are rusty, but it's superficial, they are not pierced. They are paved with rubber tips that protect the floors from friction with the metal tube. The top of the seat measures 36 cm by 31 cm. The seating height is 43 cm. The gap between the front feet is 33.5 cm. The gap of the hind feet is 50 cm. They are really very graceful, and the reinforcement tube on the side, pin, brings a nice dynamic to the general line. The seat is narrow and deep, topped with a slightly flared back upwards, which accentuates the lightness of the drawing. They were simply waxed with natural beeswax, which stops the rust, and to maintain them, it will be enough to rub them from time to time with a clean cloth.
