Vintage Herda mid-century adjustable desk lamp

Vintage mid-century table lamp by Herda with a flexible arm and shade. The adjustable arm can move up and down the pole and move back and forth. The shade itself can also be adjusted. The piece is made out of metal and aluminium. It requires an E27/26 lightbulb and currently has an EU plug (works outside the EU with a different plug or plug converter). Condition: Good. The lamp is still looking good. The aluminium shade is not perfectly rounded due to its flexibility, see last pictures. Dimensions: Shade diameter: 18 cm, Height: 45 cm, Width: 15 - 40 cm.
