Is this original Oliver or aftermarket reprint?

Aftermarket reprint produced by Jensales, the leading vintage equipment manual publisher. The content is the same factory shop information; the binding is professional reprint quality.

About the Oliver 1850

The Oliver 1850 was produced from 1964 to 1969 by the Oliver Corporation at the Charles City, Iowa plant. Available with three engine options — a 6-cylinder Waukesha gasoline, a 6-cylinder Perkins diesel, or a 6-cylinder LP-gas — the 1850 produced approximately 90 to 92 horsepower depending on fuel choice. Paired with the Hydra-Power Drive partial Power Shift transmission, it was Oliver's premium row-crop offering during the company's final independent years before the White Motor Corporation acquisition reshaped the brand. The 1850 has a strong restoration community because of its mechanical sophistication and the relative scarcity of factory shop information today.
