Thanks, Terry. I thought that the "Titanic" was probably never an Airfix 1/600 model.
Sorry for the "Senior Moment" over the Devonshire. In the online listing that I used as a format for the list, it was listed as a "cruiser" and my mind instantly thought of three funnels and flush deck rather than "Guided Missile Destroyer". Because I had built one of these kits in the 1970s, I cannot believe that I made such a stupid mistake!
