No 6212 Duchess of Kent at Rugby in late 1938 with the non-standard Midland Railway pattern ten bolt dog ring smokebox door that wasn't altered until a heavy repair in 1939. Its original 9 ton tender was replaced with a 10 ton tender in July 1936 and at the same date the sanding was modified from gravity to steam operation. 6212 was one of five engines built with roller bearings to its pony truck axleboxes with their distinctive domed covers. It has been fitted with a Hasler speed recorder, the gearbox for which was mounted on a bracket from the platform and driven by a return crank on the trailing coupled wheel. The prominent drive shaft ran horizontally from the gearbox before turning up to the front of the cab.

Ian R Townend says "I don't think the Hasler speed recorder was fitted until 1938"
