These photos were taken of the engines in storage or as found. Most were rescued from iron-dealers' scrap piles, except for the Fairbanks-Morse, which was lifted by crane from the bed of the American River about 1990.

The Fairbanks-Morse is a 1919 Model Z, 6hp throttle-governed gasoline start, kerosene run engine. It has required the most work, but has been restored to running condition.
These are two of the pumps I have. On the left, with the large rusty gears is a fire pump from the late 1800s. Toward the top of the picture is the 3-cylinder low-pressure side, and in the front, under the inverted 'U' iron, is the single cylinder high-pressure side. I've no idea what the pressures were, but it's pretty impressive. The gear on the right end, higher than the others is 18" in diameter. That should give you an idea of the size of the machinery. To the right is the expansion chamber of the Goulds pump, 5" bore X 6" stroke.
Another view of the Goulds pump, with the red body of a centrifugal well pump to its right, and the flat-belt pully from the Meyers pump behind it.
