Sweden's Landsverk firm designed several advanced light tanks, including the 20 mm armed L-60, which also had welded construction and some sloped armor. The L-60 was adopted as the Toldi light tank by Hungary. With its 20 mm gun it was roughly comparable to the German Panzer II or Soviet T-60. The L-60 was also the chassis on which the Landsverk L-62 self-propelled 40 mm anti-aircraft gun was built. Although designed as tank destroyer, the vehicle saw service with Hungarian forces on the Eastern Front as a self-propelled anti-aircraft gun under the name Nimrod. Six were used by Finland after 1942.
