50s industrial accordion wall light

Beautiful lamp, workshop wall light from the 50s. Accordion model. There was work to do! I scraped it, cleaned it then I applied a colorless rust inhibitor and finished with a colorless glossy varnish. I changed the cable. Good condition except for wear and tear from use and time (see photos) it works. Dim: l: folded: 40 cm unfolded: more or less 1.00 m h: 33 cm l: lampshade: 14.5 cm.
