In need of an engine made by the Diamond Engine Works Co of Minneapolis, MN. This is a large 70 horse power 4 cyl engine made around 1910-1912 for the American Gas Tractor. Diamond also built these engines for powering saw mills, pumping stations, electric plants, hoists, shovels and dredges. The engine looks a lot like a Holt 75 except the intake and exhaust are on opposite sides. It is likely that some of these engines were re-badged by other companies or the Diamond Iron Works tag could be missing altogether.
Any information or leads appreciated,
