Longtime reader and vintage car and engine enthusiast David Kolzow sent in this very interesting period photograph of a bridge under construction near La Moille, Illinois, likely sometime in the 1905-1915 era. A belt can just be seen running from the rear of the engine, perhaps driving a mud pump.
David didn’t identify the make or year of the engine, but it’s a Double Efficiency made by Fuller & Johnson Mfg. Co., Madison, Wisconsin. Available from 1905 to 1913, there were two different types of DE engines; a line of 3-9 hp pushrod engines (of which this is one; probably a 3 hp) and a line of 8-20 hp sideshaft engines. Of headless design, the cylinder and water hopper were a single large casting.
