of water troughs on the main line. Withdrawals took place between June 1876 and November 1888. * Number assigned, but possibly never carried (b) 6 ft 6 in driving wheels ('Small Bloomers') Eleven smaller examples were built with driving wheels in 1854 for use on secondary fast main-line trains and branch lines of the Southern Division. These engines were originally intended by McConnell to be a 7 ft-wheel variant of his Patent class, but the design was altered by order of the directors to a smaller version of the successful Bloomers. Like them, the design was closely based on the Bury, Curtis & Kennedy 6 ft single of 1848; McConnell called the Small Bloomer design 'Bury's Improved'. Seven were built by R and W Hawthorn and four by Vulcan Foundry. A further twenty of this design were built at Wolverton Works between 1857 and 1861. Numbers originally carried were an assortment from 2 to 381, renumbered 602 to 981 in 1862. Two were withdrawn in 1866, but the others were rebuilt between 1868 and 1876; the last one was scrapped in 1887. (c) 7 ft 6 in driving wheel(H-class 'Special Bloomers') Three examples were built by Wolverton Works with driving wheels together with McConnell’s patented firebox in 1861, which were intended for the fastest expresses. They were heavier than had been planned, so a further two engines, ordered and under construction, were cancelled in February 1862. This led to McConnell’s immediate resignation. The three completed engines (Nos. 372/3/5) went into store, so hardly ran in their original state. One of them (No. 373) was put on show at the 1862 International Exhibition in South Kensington from May to November 1862. After rebuilding with normal boilers in 1866/7, they worked until withdrawal in 1880 and 1882. Many years later, they were described as "Extra-large Bloomers". Replicas An accurate full-size, non-working replica was built, by apprentices, for static display outside Milton Keynes station in 1991. It represented the type as in 1873–76 condition, was numbered '1009' as if to follow the last of the class, 1008, and was named 'Wolverton' to commemorate the Southern Division Works, although no engine was so named on the LNWR. It was taken into Wolverton Works (then owned by Alstom and later by Railcare) in 2006 for renovation and repainting. The renovation was funded and carried out by the various owners of Wolverton works and latterly by
