Data from Entry 218, "Model of 'Bury' Passenger locomotive (working)1907 Catalogue of Mechanical Engineering Collection in the Science Division of the Victoria & Albert Museum, South Kensington ( London, Pub. for H.M. Stationery office 1919), p 113; and Francis Wishaw, The Railways of Great Britain and Ireland (London: Robson, Levey & Franklyn, 1842), pp, 332,
See Locobase 653 for a discussion of Bury's D-shaped firebox design. These used bar frames, an unusual choice for a British builder in those days of plate framing.
