Modified Conventional Pattern Trucks

[Konstantin Chernov]

Hello.
Sorry for my poor English.
1.Chevrolet Holden model 1941.I believe this truck was assembled on the Canadian Chevrolet Maple Leaf 1543 chassis.
What was this car called in Australia? Did the springs strengthen under the army wheels? Have changes been made to hubs and brake drums?
2.Chevrolet 41-E22 model 1941 with 20mm Breda Model 35 anti-aircraft gun. Is this truck completely assembled in Canada? Marker lights over the headlights - is it a requirement of the Canadian or Australian army? 41-E22 is an Australian denotation?
3.Chevrolet Maple Leaf with the same marker lights on commercial wheels and left-hand drive.Is this Chevrolet Maple Leaf 1543?
