You're forgetting the best known example of quadrigas which is the on top of the Berlin Brandenburger tor.
This chariot with four horses in front was also recently renovated. The Wayne county building quadrigas are also mentioned in the wiki, with a picture no less!
The stues with staffs.
The Minnesota State Capitol quadrila [[glod plated!) still retains the staff, even though it does resemble the Berlin quadrila.
