Vintage side table

School drawing table 1960s. Original dark brown metal base, the wooden top is tiltable and can also be raised or lowered (minimum 94 cm from the floor - maximum 112 cm from the ground) using a joystick on the right side. All tables work. The attached photos provide details of each tray. The trays can be kept as they are (trace of time, engravings of schoolchildren) or replaced by a more noble material.
