No pictures of any of these engines are known to exist. The Transfer records mention "2 engines of 23 ton's weight, 1 second-class coal/wood burner of 15 tons, 1 English make, American built of 15 tons, and 1 second class engine of 12 tons." The use of the "Enoch Pratt" label is questionable, although it may be the "American built of 15 tons" mentioned. A 2-2-2 wheel arrangement is unusual. The Robert Stephenson Patentee locomotive of 1834 was of this pattern. American manufacturers known to have copied Stephenson's work from Britain include Baldwin Locomotive Works, Rogers Locomotive and Machine Works, the Locks & Canal Company of Lowell, Ma., and the West Point Foundry. No extant records support the sales of an engine from any of these companies to Eckhart. The West Point Foundry had supplied the machinery to the Georges Creek Coal and Iron Company or the blast furnace at Lonaconing.
