In the early 1930s, Volvo had suddenly become an established manufacturer of (reliable but old-fashioned) light and medium-duty trucks, and also a recognised manufacturer of heavier trucks (in small numbers) of modern design.
The LV-series - small modern trucks
The light to medium-duty trucks from Volvo up to 1932 were not very modern, having two-wheel brakes and wooden-spoke wheels. It was obvious that a more modern smaller truck was needed. The resulting LV71 and LV73 series proved to be very popular, to such an extent that these two truck series can be said to have established Volvo as a major exporter of trucks, often to countries remote from Sweden (which was to be expected, since European countries in those days normally had national truck manufacturers of their own, creating extremely fierce competition for import vehicles).
Designed for different transports
The differences between LV71 and LV73 were mainly in the chassis, to cope with various transport applications. (LV72 and LV74 were identical to the LV71 and LV73, but with a longer wheelbase). The more popular truck series of these two was the (cheaper) LV71/72, which was primarily intended for distribution transport on roads, while the LV73/74 had a larger margin for overload, and was for this reason more suitable for off-road construction purposes.
