FN – other models: the collective page of the 4RM 62C type from Fabrique Nationale de Herstal, six-cylinder with 4.3-litre displacement, gross weight up to 8,015 kg
This page gathers the truck type 4RM 62C from the Belgian maker Fabrique Nationale de Herstal (FN), which appears in the register under two spellings, 4RM 62C and 4RM/62C. Besides weapons and later motorcycles, FN also built trucks before that division ended in the 1960s. The designation 4RM points to four-wheel drive, intended for construction-site and off-road use.

The register lists 2 versions here with a uniform displacement of 4,275 cm³ from six-cylinder engines, kerb weights from 3,670 to 4,285 kg, gross vehicle weights from 5,731 to 8,015 kg, and lengths from 5,670 to 5,700 mm with widths from 2,230 to 2,320 mm.
With gross weights up to 8,015 kg, the 4RM 62C belongs to the medium-duty truck class used in the post-war period for regional freight transport and municipal tasks in Belgium and neighbouring countries; the small number of versions carried reflects the limited scale of truck building compared with FN's other divisions. With four-wheel drive, the 4RM 62C suited use on unpaved roads and construction sites, serving both civilian and military purposes.
For this historic type, check the frame and axles for corrosion, clutch and gearbox condition, brake system operation, and the availability of parts, which, with truck production long discontinued, can now only be found through specialised vintage-vehicle parts dealers. As FN is mainly known today for weapons and motorcycles, enthusiasts of historic commercial vehicles are often the best source of information on technology and restoration.
