Later that year, in the 1862 International Exhibition, The LNWR exhibited a locomotive and tender fitted with the "Apparatus for supplying water to tenders whilst in motion". The catalogue made note that this was the same class that ran the "American express" on 7 January, but the locomotive selected was No. 531 "Lady of the Lake", rather than "Watt" itself. The "Lady of the Lake" was awarded a bronze medal, and the entire class became known to many as the "Lady of the Lake" class.
