Vanaja – other truck models: the collective page of the Finnish manufacturer (1943–1968, Hämeenlinna, later absorbed into Sisu), six-cylinder engines from 92 to 220 kW, 9.6 to 17.85 t gross weight
Vanaja was a Finnish truck manufacturer based in Hämeenlinna that operated from 1943 to 1968 before being absorbed into the Sisu group. This collective page lists models the register could not assign to a named range; the type abbreviations follow Finnish registry logic, such as "VAK" for chassis series, "A" and "N" for different axle configurations, and the terms "Avolavakuorma-auto" (flatbed truck) and "Puoliperävaunun vetoauto" (semi-trailer tractor) from the Finnish vehicle register.

The register lists 37 versions here with 92 to 220 kW, all with six-cylinder engines of 5,760 to 16,867 cm³ displacement. Gross vehicle weight runs from 9,600 to 17,850 kg, lengths from 6,750 to 9,650 mm, and widths from 2,330 to 2,500 mm.
As one of the few domestic truck makers in post-war Finland, Vanaja mainly supplied the home market with flatbed trucks and tractor units for timber haulage, construction and long-distance transport, before the brand was absorbed into Sisu as the Finnish commercial vehicle industry consolidated.
On these historic vehicles, buying used is mostly about the preservation state of the frame, cab and axles, since parts for the six-cylinder engines and chassis are now mainly sourced through collector and vintage-vehicle networks and through Sisu successor parts. Rust on the frame rails and leaf springs is the key check point for vehicles of this age.
