Another good unit for assemblers is the Bergmann, a V type with aluminium cylinders, having steel liners and vertical overhead valves directly operated by an overhead camshaft, no gear being used between the cam and the valve stem. This engine has a cast iron detachable head, and is built as a unit with the change-speed gear. It is the work of one of the most reputed German engineers, and is undoubtedly a fine piece of work.
