Ten points for you Gadge. A common rule of thumb for a simple visual check on whether a king-pin and stub-axle steering system is actually Ackerman, is whether, with the wheels in the straight-ahead position, a pair of lines through the king pins and the tie rod ends, intersect on the vehicle centerline at 2/3 of the wheelbase length. Real mug-amateurs make them so that those two lines are parallel to each other.
That machine seems to be quite decently engineered - well above normal ride-on standards.
