I think that any aircraft designed post-1950 to operate in the trans-sonic region would have a laminar flow wing. For example: the De Havilland Venom was a Vampire with a laminar flow wing. Supersonic aerofoil sections are whole new subject. This may be of interest http://www.aae.uiuc.edu/m-selig/ads/aircraft.html That said that list shows a different NACA number for the Spitfire to a contemporary paper so ...
