Black desk lamp, design, vintage

A sturdy black desk lamp that can be clamped to the desk lamp. Unfortunately, the screw with which you can clamp the lamp is missing. We are already looking for an old copy, but unfortunately we have not found it yet. The black vintage desk lamp is in very good condition and has been rarely used. Everything works as it should.
