Wood brass glass sconce

Charming wall lamp with a solid wood base varnished (aged appearance), on which is fixed a brass "arm" (or perhaps bronze?), where is suspended a lampshade in thick amber glass on which are painted floral motifs and which has a strapping (removable) at the bottom in gilded metal (brass?). I don't think it's the original glass because I have an identical wall lamp with another glass. At the back, it has a fixing tab. This application probably dates from the 80s. The whole is in good condition, solid, just stains on the metal strapping and a small lack or sinking on the lower left corner of the wooden base. Electrification (connecting cables and socket for large-end bulb) appears to be functional. The base is 39 cm high and 17 cm wide (widest). The depth (or wall spacing) is 26 cm (including glass). The glass part has a diameter of 20 cm. The set weighs 1.6 kg.
