Please email with any questions. 7" by 8" illustrated statement of account from James Leffel & Co. in Springfield, Ohio, manufacturers of the Bookwalter Engine and Leffel's Improved Double Turbine Water Wheel. Date is hard to pin down exactly but must have been in the early years of the 1880's since someone wrote an 8 over the number 7 of "187_". Nice condition for the age, slight soiling and fold lines from the original mailing to the suctomer in Macon, Georgia.
