Mullins trailer for sale. I have a valid certificate of registration for this trailer. I planned to redo this trailer to haul behind my Model A Vicky on a cross-country trip however age has changed my plans. Needs painting to match your car and new wiring. I was told it has an original Mullins trailer frame with a fiberglass body from the 60's. Comes with new Model A LED tail lights, marker lights, locking latches and a lighted license plate frame.
