Data from "The Locomotives of the Great Eastern Railway", The Locomotive, Volume 16 (15 September 1910), p. 185. Three builders turned out 50 locomotives to this basic design in 1875-1878. Neilson & Company delivered 25 (works numbers 2013-2037) in 1875. Robert Stephenson & Company added three in 1876 (works numbers 2211-2213), and seven in 1877 (works 2214-2220). Kitson & Company supplied the last 15 in 1878 (works numbers 2201-2215).
These tanks came with two basic profiles. The first ten Neilsons--road 211-220-- headed for the GER's North Woolwich branch were cropped to fit the loading gauge by adopting a flat-topped dome and short stack. All of the others had the round-topped dome and taller tapered stack. A considerable gap of 11 ft 7 in (3.53 m) separated the two coupled axles under the smokebox and dome and the bogie underpinning the firebox and bunker. The flat-topped Neilsons would later be refitted with the standard stack.
Data from Richard Marsden's LNER site -- [] (Jan 2004) . See also "The Locomotives of the Great Eastern Ry", Locomotive Magazine, Volume XIX [19] (15 March 1913), p. 58). First four delivered in 1898, sixteen in 1899, fifteen in 1900, and five in 1901.
