Vintage Living French A Complete Language Course Vinyl Record Set

Vintage 1950s Livinf French - A Complete Language Course, 40 lessons on x4 vinyl records long playing 33-1/3 rp. Housed in original cardboard box, records still in original plastic sleeves. Comes with x2 books, a conversation manual and an English/french common usage dictionary. I have attached screenshots of the included books to show what they look like as the ones in this set have been nicely covered by the previous owner and I did not want to damage the books by removing the covering, so books are in excellent condition. Cardboard box in fairly good condition considering its age, I have shown in phos x1 corner has a split only.
Records untested as I don’t have a player, so I can’t speak as to their quality, however I do remember my mum listening to them when I was little!
