Cosack stem lamp

Cosack articulated stem lamp, 50s, nicely patinated (visible on the photos), the electrical system has not been touched but the lamp has been plugged in and working. The switch is not currently connected to the electrical wires (however no problem for a simple connection as a wall lamp). The lampshade is not original and its attachment system has obviously been modified to be adapted to the lamp (DIY invisible once the lamp is assembled), so it is not part of the sale but will be shipped "as a gift".
