Last time I was in France (1997), the Oceanographic museum in Monaco (right next to Nice) had an exhibit of Cousteau equipment that was pretty cool.
No idea if they still have it or not.

Ended up having a great conversation with one of the docents there and the next morning he took me out on his boat, loaned me a full set of dive gear, and we dove the cliff area right below the museum. Mark
