1894 'Two steamers recently built for carrying petroleum in bulk by Messrs. David J. Dunlop and Co., Port Glasgow. They were constructed to the order of the Anglo-American Oil Company, Limited, for their service between the United States and the United Kingdom. The steamers are on similar lines to, but larger than, the s.s. Manhattan, built by Messrs. Dunlop for the same owners about 3 1/2 years ago, and which has since proved herself a very successful and economical steamer in the Atlantic petroleum trade. The two new steamers, named respectively Delaware and Lackawanna, are each 345 ft. long between perpendiculars, 44 ft. broad, and 31 ft. 6 in. in depth, .... The main pumps, of which there are two, were made by the Snow Steam Pumping Engine Company of New Jersey. ....'[2]
