I do not have the book with me, but I have photocopies of some illustrations and the list of figures, but it may be useful. Check out - Andre, George F. 1878 "A Descriptive Treatise on Mining Machinery, Tools and Other Appliances Used in Mining", Vol. II. London and New York: E & FN Spon. A Lefell engine is illustrated frm various perspectives in Figures 588-593 and a Parker Pump is indicated as being shown in Figs 564-576. There may also be written descriptions in book, but I do not have them. Other mining texts from that period may also be useful. -James Wettstaed-
