School stool in metal and industrial style wood

School or workshop stool (Mullca? Without any certainty), mix of vintage with this pretty typical green blue color (school memories of the 50s or 60s) and industrial with its tubular steel base and its wooden seat. This stool is in good condition (stable, no concern for strength) but in its own juice, I leave you the pleasure to decide what you will do :) It presents the marks and wear of its age and its use by schoolchildren: red and blue ink stains, scratches, scratches, lack of varnish on the wood ... Some brown colorations and some pictured area (superficial rust) on the base, the blue-green color is still visible on the uprights, but has almost completely disappeared from the horizontal tubes, leaving a patinated gray steel around the seat and a shiny steel polished by the feet of schoolchildren on the horizontal bars low . It is provided with 4 rubber pads (original I think). It is 45 cm high, the seat measures 31 cm by 31 cm. And 40 cm by 40 cm at the base. It weighs nearly 5 kg.
