Landsverk L-100 and 101

Landsverk L-100 (L-100) was a prototype design by Landsverk in 1933-34. It was designed as an ultra-light tank weighing just 4.5 tonnes. It was armed with a single machine gun, Its max speed was 55km/h. It never entered service with the Swedish army. The only known photo (see photo link) of the tank indicates also a 20mm gun version maybe installed later on to the prototype.

Landsverk L-101 which actually preceded the L-100 was an ultra-light weight tank destroyer armed with a 20mm Cannon. This design never got beyond the drawing board.
