Landsverk L-210 Armored Motorcycle 1930
By the early 1930s, the Danish military was investigating whether a cheaper alternative could be found to conventional armored vehicles of the day. In 1932, Landsverk produced a new type of armored motorcycle based on specifications provided by Danish authorities, internally known as the L-210. This vehicle received the official designation Førsøkspanser 3 (F.P.3, Trial armored vehicle 3) in Denmark.
It was based on a Harley-Davidson motorcycle equipped with a 1200 cc (cubic centimeter) V2 engine capable of producing 30 horsepower (22 kW). This type of motorcycle was already in use by the Danish army at the time and the F.P.3 could thus benefit from parts commonality. The motorcycle in question was most likely a Harley-Davidson VL which first entered production in 1930. This vehicle was equipped with a single-wheeled sidecar carrying the armament which was placed to the right of the motorcycle. This armament consisted of a Madsen light machine gun which was mounted behind a gun shield and chambered for 8×58 mmR Danish Krag ammunition fed from a top-mounted curved box magazine.
