Pic #1 #2 The Toldi II got stronger springs but not weaponry until 1942-43 when they got a 40 mm gun finally and thicker armor (Toldi II/A). The Toldi III was never finished, I'm not sure how it would differed it was an obsolete light tank as well.
Pic #3 Another version of L-62 was turned into an ambulance tank and called Lehel.
Pic #4 They also designed a tank destroyed on the basis of the Toldi.
