The creation of the Landsverk L-170 was initiated in 1929, but not completed until 1932.  At that time, the vehicle went into military service and its name was changed to FM/29.  Although performing fairly well, only one vehicle was built due to its relatively high cost.  Although not used much as a front-line vehicle, it saw very active use as a driver's training vehicle, not being retired until about 1946.  It was nicknamed "Paddan" (translated as "Toad" in Swedish) due to its close resemblance to the amphibian.
