For Benjamin Gibbons. Level Iron Works, Brierley Hill, Staffordshire. Note that the Catalogue of Old Engines says that this engine was erected in 1810. However the engine erected at Level Iron Works in 1810 was a 42 inch engine coded TT [see Portfolio 5/679a above]. The drawings for this engine were placed in the same book as those for the 42 inch engine of 1824 [see Portfolio 5/679c above].
