As far as I came up the idea about wheels with spokes looking exactly at this armoured car, I think, I had to build such model.
Unfortunately, I did not find enough documentation: almost all photos I found had not very good quality and pictures contained contradictory information. So, this model is a mix of various pictures, photos and ideas. Very good page with information about this AC is here:

This time I tried to make black bottom. Exhaust pipe is flat, but it is almost invisible.
