For The Albion Mill Co. Flour mill, near Blackfriars Bridge, London. This second engine was formally ordered in Jun. 1787, although work for it had been under way long before then. Albion Mill burnt down in Mar. 1791, but this engine was undamaged. It was taken back by Boulton & Watt and sold to Don Diego Gardoqui as a blowing engine for Cadiz in 1793.
