Again wrong. There is for example Agenzia Luce in Italy and Arka in Paris, France. AFAIK there is also one in Australia, too. Agenzia offers almost all BW films as slide, and Arka has recently extended its range of films, too.
I'd like to add that there's nothing "magic" in b&w reversal. Many formulas have been around for centuries. What one does pay is the work that's behind the curtains, work that is necessary to find the proper parameters for each and every emulsion that can be reversed.
