Art Deco ceramic wall lights, adjustable arms

Magnificent burgundy ceramic wall lights with two arms. Art Deco period. The width of the arms can be adjusted as desired (a small ceramic "nipple" that screws in or out to achieve the desired width). In good condition, I note a tiny chip on the fitting of one and slight (original) marks on the glazing. Details are visible in the photos. Dimensions: Height: 17cm. Minimum width: 17cm. Depth: 13cm. This uncommon and period wall light model is the detail that adds a touch of originality, elegance, and character to an interior. ‼️‼️ Original wiring untested, consider a possible replacement ‼️‼️.
