LMS 5MT 4-6-0 No 44920 with the 4.38pm Marylebone-Nottingham near Great Missenden on 30 June 1966. The smokebox door has 'Wild Thing' chalked on, a feature seen on other GC locos during this year so perhaps a certain crew liked to add this. The Troggs single of the same name was released in April 1966.
