70s ceramic lamp

Stoneware lamp enameled with coarse salt, artisanal lamp signed cfy, potters who according to my research based in Brittany but I would like to know more….unique piece from the 60s/70s, well made and thick in material, h30 cm 30 cm), the only small downside is a shock to the collar (see photos) which is not visible with the lampshade, the two small broken ends were glued just below the accident on the neck…...way original to repair….the lampshade (h40cm X 35cm) was on the lamp when I found it and gives a warm light (bayonet socket bulbs),.
