Data from "Contractor's Locomotive Tank Engine", Engineer, Volume 67 (10 May 1889), p 395.
The Engineer commented that this builder had "perhaps done more in locomotive work than any other firm in what is known as the agricultural engineering trade." The report added that Engineer needed "scarcely say that the workmanship and material leave nothing to be desired. This firm long since attained a reputation for these things which they are not likely to sacrifice."
Although the drivers were cast iron, many of the other components used Bessemer steel.
Data from "Locomotive Engines at the Paris Exhibition", The Artizan, Vol II, 4th Series, #2 (11 February 1868), p. 27 and "Sir David Campbell on Railway Apparatus", Reports on the Paris Universal Exhibition 1867, Volume IV (London: George E. Eyre and William Spottiswoode, 1868), pp. 497.
The other of the two contractor's engines shown in the English section of the Universal Exhibition at Paris (see Locobase 11162 for the Hughes locomotive), this had the saddle tank mounted relatively far forward. Campbell commented on the fitting of "Clark's smoke-consuming apparatus", the fitting of the injector on the barrel of the boiler, and the extensive use of steel in the locomotive's "motion works".
