JB in response, I have followed the Pullman cars that were located at Seaburn from their arrival in the late 1980's on site to their removal two years ago (35mm Colour Slides). I can advise that only the BR Mk1 coach named "CHRISTINE" was scrapped on site due to its condition. As to the three Pullman cars "SAPPHIRE", "ROSALIND" & "PADUA". They left Seaburn by road haulage to Barrow Hill, Chesterfield. Following assessment of each cars condition they were then moved to the East Kent Railway for restoration. I am advised that the long term future for the cars will see them relocated on completion of each restoration to the restored Folkestone Harbour Station as static Restaurants.
Coincidentally, I am currently scanning "The Pullman Lodge" Seaburn slides to 'jpg' format.
