Charles Jourdan navy suede brogue heels

These are navy suede with stitched leather trim and laces, marked 6 on the sole, Charles Jourdan Paris in gold on the inside. I'd literally only just read about Charles Jourdan in Shoes A- Z when I saw these in the shop! Got so excited now I want to know everything about them! I would like your help in dating them. I've not been able to find another picture or advertisement for this brogue close toe style CJ shoe- they seem to be mainly classy court or open toe heels. I have written to the current Charles Jourdan customer service to see if they kept any record of it. Any suggestions of date and reasons welcome.
