Trucks for the Presidential Car

I am just about done with the design of the trucks for the Presidential Car, United States. It took more than seven iterations to get the design right. I still need to add the brake linkage, the bottom bar  under the pedestals. Once I have two trucks complete I will work on the trundle truss that connects the two trucks.  I went with black and gold paint scheme, as red wheels that some others have used seemed out of place on a funeral car.
