Editor’s note: This engine came to us with little information.?Here is what we’ve found: Ernie (, senior member of writes: “F and G was Fitzhenry-Guptill. They made orchard spraying equipment. Most are from Cambridge, Mass., but some have another city name near Boston. Yes, they do look like marine engines. They are quite common in New England. Some are headless and some have removable heads. Most had a large drip oiler with a large single glass and four or five needle valves to adjust the individual oil lines. I havn’t seen one with a govenor. They had a rather nice brass carburetor with a fine adjustable throttle quadrant.”
