Desk lamp - Iron

Antique industrial-style desk/table lamp from the 1950s/60s, with a metal frame, equipped with a flexible arm that allows the arm to be lowered or raised, and with movement of the light direction to the right and left as documented in the photo.
The lamp in question comes with all the original parts from the era.
On/off switch with two brightness modes; the first mode is somewhat faulty, the second mode works perfectly.
The plug has been replaced.
The E27 bulb socket will be supplied with the original bulb.
