Lot of 4 Mullca 510 school chairs

Set of 4 chairs mullca 510, the reference school chair designed by gaston cavaillon, many of whom keep an emotional memory. The tubular steel structure of each model is in very good condition, the beech seats and backs are rather well preserved in terms of the use that was made of it (see the 6 to 7 photos each) and they stack perfectly. Two of the chairs have reference parts stamped on the back of the seat these chairs have been completely cleaned and especially rid of their dried chewing gum without which they would not have been real school chairs...
