Vintage Idell 6751 brass desk lamp Bauhaus by Christian Dell for Kaiser

Art Deco desk lamp from Kaiser, notable at the ball joint of the shade. Model 6751. Designed by Christian Dell. Completely out of brass. The lamp is in very good used condition. It has few oxidation spots and few little scratches. The inner shade is in good condition and it has beautiful decorative oxidation. The plastic ring on the pressure switch is yellowed. The bottom is covered with leather. Certainly small signs of age and wear, which is normal at that age, but the overall impression can really still be described as beautiful.
