The whereabouts of one of the original nameplates from Ralph Brocklebank is known to be held by the LNWR Society. The other was sold at an Adam Partridge auction in Liverpool in 2015 at a hammer price of £6,600. Consequently, the buyer then seems to have turned it round to the Great Central Railwayana Auction at Stoneleigh on the 10th March 2018 where it realised £8,800.
The original locomotive was part of the Claughton class designed by Charles Bowen Cooke and introduced in 1913. It became famous for two magnificent trial runs, made over the LNWR main line in 1914. Showing what the design was really capable of, it set new standards of power for British express locomotives. A maximum indicated horsepower of 1669 at 69 mph was recorded just above Tebay on the climb to Shap with the maximum permitted load of 360 tons.
