NOTE: Ref. sales brochure dated August 15, 1901
When you view the 1901 engine note that the exhaust chamber/manifold(2) lies on top of the cylinders. On the 1903 engine (this web site), the exhaust chamber/manifold is on the bottom of the engine (not visible). A picture (not in this site) of the 3 cylinder engine in the sales brochure dated August 15, 1902 indicates that the exhaust chamber/manifold had already been relocated on the bottom of the engine.
The throttle slide(3) increases or decreases the amount the intake valves can open. The naturally aspirated intake valves give one the impression that the engine is two-cycle but it is not. The intake valves are keep closed during the power cycle by the expanding gases and the exhaust valves are open and closed by a cam shaft (visible in image).
Note how compact the transmission(5) is and how it is recessed part of the way into the flywheel. The transmission has two forward gears and one reverse.
Note the wire on the right side of the exhaust chamber/manifold(2). This is a single wire that carries the charge from the belt-driven magneto to three anvils located above the intake feed pipe/manifold(4) and just below the exhaust chamber/manifold. The center anvil is slightly visible.
The empty threaded hole in the cylinder nearest the flywheel is for an oiler and there would be one in each cylinder. The three mechanisms on the cam shaft are the sparker activators and would be covered up if the top part of the oil pan was on the engine.
Engine: 4-cycle , water-cooled

Peter seems to think this carburetor is original and so does your site host. He has indicated in a letter that the threaded rod to left and top is the needle valve and is an integral part of the top of the float. The 1/4 inch tube to the right and top is a vent tube and is twelve inches long. Peter does not say in his letter but your site host believes the lever with the hole in it is the choke lever. This carburetor is on a 1903 Duryea 4-wheeled Phaeton.

Your site host has no reason to believe that the lamp on the Duryea in image 1 is not authentic and an original accessory. The rectangular side lens and round front lens are beveled. The body (center) is steel and is lined with brass inserts. The finials are brass and the quality of this lamp is very high.

NOTE: The Library staff at Rutgers University checked
the Newark City Directories for me and found an entry for the
Newark Coach Lamp Mfg. Co. at 84 Monroe Street in volume
1902-1903.
NOTE: The staff at the Newark Public Library checked the
Industrial Directory of New Jersey for me and found entries for
the Coach Lamp Mfg. Co. of New Jersey up to 1906, but did not
indicate when the entries began.
UPDATE: The staft at the Newark Public Library has found an entry for the year 1901.
The information in this section refers to image 7.
The brass hinge in image 7 appears to have been nickel plated and then had a gold leaf or gold wash applied to the top surface of the hinge. Dimethylgloxime is needed to check for nickel and there is none to be had locally.
On my browser blotches of gold leaf (or gold wash) stand out very distinctively.
Markings None.
Measurements Length is 4 1/2" - Width is 1 3/4"
NOTE: Nickel - 1751, New York Public Library
NOTE: Electroplating - 1840, New York Public Library
