Development of the L-62 began in 1931, with the Landsverk company choosing to convert their L-10 light tank into an SPAA unit as part of a plan to create a range of vehicles intended for the export market. During development however, Landsverk created the more advanced L-60 tank, leading to the decision of continuing development of the L-62 on that chassis instead of the previously used L-10.

The first prototype of the L-62, named ANTI I, was built by the end of the 1930’s in parallel with the L-60 then tested. While the Swedish military didn’t express interest in procuring the L-62, the Hungarian military purchased the production licence for both the L-60 and L-62, resulting in the creation of the domestically produced 38M Toldi and 40M Nimród tanks, respectively.

Landsverk continued developing the L-62 into the early 1940’s, creating a more advanced version of the L-62 in 1941, called the ANTI II. The improved version featured a new hull and turret, as well as having its German transmission swapped out for a Swedish one.

A total of six L-62 ANTI IIs were built, all of which were purchased by Finland and subsequently used in action throughout the remainder of WWII. Surviving the war, the L-62s were used as training vehicles in the postwar period and right up until their retirement in 1966.
