King's Wimbledon certainly possesses one of the nameplates - I'm unclear whether post-withdrawal, or as a presentation item at the naming (the school also has a 7mm scale model of the locomotive, in display case).
There is a list on Wikipedia which records where a number of the nameplates are to be found. ‘List of SR V “Schools” class locomotives’.
At leats one squadron nameplate from a 'Battle of Britain' loco was presented to the RAF and exhibited in a Forces' museum.
I think that Spitfire, Hurricane and (possibly) Fighter Command nameplates, either original or presentation, were at Bentley Priory, Fighter Command Headquarters. When it closed they went to the RAF Museum at Hendon.
