These date from 1835 and 1844 and give the cost of the two engines along with other components and work needed to install them. In addition to this there is a list of components for the 1835 engine that were transported by Mr John Hargreaves from Manchester to Lancaster for Coates and Wright. There is also a note dated 1859 written by Coates giving a history of the two steam engines installed in the mill.
